Soil Behavior SOIL BEHAVIOR Soil behavior involves all the processes occurring on the surface of the earth as a result of the agents of the very processes. This research paper explores the characteristics of soil under: liquefaction, soil improvement, geophysical methods, excavation safety and intelligent compaction. A case study for geotechnical failure will also be provided.
Liquefaction is the process by which the earthquake or heavy material on the earth surface causes the earth materials to reduce in its stiffness and strength, thus rendering it vulnerable to erosion by the erosion agents. It occurs majorly in soils that are water saturated. All air spaces in this kind of soil are filled with water. Before the impact of the earthquake, soil water has low pressure, but the impact of the earthquake increases the pressure of the water in the soil, particularly between the individual soil particles (Muiri, 1990). These particles, pressing against one another, break and reduce in strength and stiffness. Developments made on the surface of the earth by human efforts exert heavy weight on the soil increasing the pressure in the soil water and this too can cause changes in the strength of the soil.
Ground improvements are the various ways by which soil engineering properties are made better in order to reduce exertion of pressure on the soil particles by the water. The properties of concern are; the ability of the soil to pass water, shear strength and soil stiffness. In this move, expensive and sophisticated materials and other tools are laid below the foundations to support the weights of heavy structures on the ground. Other techniques are also employed, e.g. dykes, tunnels, channels, reservoirs and embankments, which have been used to reduce the impact of the earthquakes. This reduces the water pressure on the soil particles. This is done by engineers depending on the size of the structures and the intensity of the earthquakes in the region.
Geophysical methods are the methods used to collect data, relating to waves, in the soil. These are; Direct Current Electrical Resistivity, Induced Polarization and Spectral Induced Polarization where directly, electricity is pumped into the ground to collect and record all the information on ground waves. Another method is Electromagnetic and Ground Penetrating Radar in which the information is recorded with no direct contact with the earth media. It uses EM waves also. Gravity and Microgravity is another method of measuring the waves using gravimeters. This method obtains the masses and densities of the soil. Apart from the above named methods, is Magnetic method, which targets mineral deposits and man-made structures by measuring local variations of the geomagnetic field to detect the magnetic fields emerging from the liquid outer part of the earth. Nuclear Magnetic Resonance is a geophysical method, which explores ground water measuring magnetic signals (Meier, 2010). Seismology and Seismic Survey is a method in which the seismographs are used to detect the waves travelling to and from the centre of the earth.
Thousands of people die from the excavation accidents. The excavation process should be done with care after careful evaluation of the characteristics of the soil. The information concerning vulnerability of the soil to collapse, and pat history should be given to guide the excavators in order to cab the menace. Other measures like Battering the excavation sides and Temporary support should be kept in mind prior to the commencement of the excavation exercise. These will reduce the accident risks during the exercise. It is also advisable to conduct frequent and thorough inspection in order to detect small deviations.

A building collapse case study
Overturned apartment complex buildings in Niigata in 1964
In 1964, in Niigata city, many buildings collapsed killing hundreds of people and causing destruction to property.
Intelligent compaction: when pavements begin to wear and become weak before their expected time, showing signs of cracking and crumbling, may be due to poor compacting of the base layer. To cab this menace, intelligent compacting rollers are used to provide uniformity and quality, enhancing long lasting performance. Frequent checkups are also recommended to detect deviations which would otherwise be dangerous. In conclusion, care and knowhow are very key in the pursuit of the said exercises, if we have to prevent the accidents.

Soil Mechanics

...Soil Mechanics Introduction Earth is extremely rich in soil and minerals and the terrain we find is of different types and kinds. Soil is made up of three components: solid particles, air, and water. The particles are classified by size as clay, silt, sand, gravel, cobbles, or boulders. The amount of air and water within a sample of soil affects its behavior. The sizes and types of particles that constitute a particular soil affect its properties and thus its load-carrying ability and compressibility. However the soil we find is hardly perfect for any kind of construction before any steps are taken to harden the soil. This is usually because soil is by natural forces in tension and shear, although it is comparatively stronger... in...

The Relationship Between Soil Properties and Soil Erodibility

...The Relationship Between Soil Properties and Soil Erodibility Introduction Soil erodibility is influenced by individual site factors such as topography vegetation, and rainfall; however, beyond these influences, the single most important factor in soil erodibility is the soil's properties, both physical and chemical (Rhoton, Emmerich, Goodrich, McChesney & Miller, 1998, p. 415). Physical and chemical properties of soil Physical properties of soil The different physical properties of soil 1. Soil Texture 2. Soil Structure 3. Soil Consistence 4....

Soil Consolidation during Construction

...SOIL CONSOLIDATION DURING CONSTRUCTION With the progress of man's demand for modernisation, different types of infrastructure have been continually conceptualised, most of which now serve as tangible necessities for man's daily life. Indeed, through the test of time, a building's aesthetics and purpose occupy the largest criteria in the field of landscape construction. However, there is one major factor which is often overlooked by other people. This is the mechanics of the soil on which the construction will take place. Soil consolidation, which is a major concern for all landscape artists, have significantly become an important field in construction. Generally, any undrained loading or...

Soil concentration

...Soil Concentration Elemental composition that is found in soils has anomalies leading to plant stress, as well as increased salt concentration (Cl-), and Ca2+ mineral nutrients. The salt concentration found in soil solutions is measured in form of its salinity. The amount of Cl- present in a given soil solution determines its salinity, which is required for proper plant life. Cac2+ is an important mineral nutrient in soil for plant life, but is harmful if in excess. The main cause of soil salinity can be attributed to the water management practices used on a given soil solution. High concentrations of Cl- destabilize...

Samples were collected and tested to achieve this objective. Site location The site is located around 13.5 miles away from the main administrative buildings. Elevation of the ground’s site was measured to lie between 52m and 64m as shown on MAP1. To ensure more control, a trial pit of 60cm X 60cm X 60cm was excavated with coordinates of N 530 3.617 and W00 57.670. The day’s weather was very appealing as there was no rain, and this made the testing of the soil... to be done with...

However, these soils receive insufficient rainfall due to the climate and it is for this reason that they always retain their soluble salts. The order of arid soils is characterized by three levels which are: Oxisol Vertisol Entisol It is however important to note that not all arid soils are classified in the aridsol order. Some have unique compositions that place them in other orders of soil. Oxisols are weathered soils found in the...
