It is critically important to carry out the analysis of soil prior to initiate any construction. The analysis of soil yields soil related various important factors that include the interaction of soil with the structure over a time through various weather conditions, types of structure soil can support etc.
The analysis of soil composition reveals that there are three types of soil namely cohesion less, cohesive, and organic soils. In cohesion less soil the soil particles remain apart from each other. The example of such soil is sand, gravel and silt. Cohesive soils consist of very tiny particles that have characteristic to stick together in presence of water due to attractive forces present among them. Clay is an example of such soil2. Organic soils have spongy, compressible and crumbly nature and because of because of its unstable nature are strongly undesirable for any scale of construction. Depending of the soil various layers depth, all three types are further divided into various sub-categories and construction is carried out while considering these sub-layers i.e. shallow foundations is located in the first layer below the structure, followed by the individual footing (sub plate) between boundary layers, and uprooting sub paneling that sometimes used extreme environments (tundra)1. As enlarge footing size will increase the area of contact (area = B2), hence it increase the allowable bearing capacity qa of soil. By evaluating all these variables, the column load can be calculated which will be equal to the load on footing. As soil degradation also affect the footing hence the effect is indirectly transfer to columns and hence to the whole construction.
In this experiment a specimen of soil with known % of water by weight has been prepared. The mass of sample is determined using an analytical balance ...Download file to see next pagesRead More
