Techniques Used for Improving Bearing Capacity of Soil The following techniques can be used for improving bearing capacity of soil as per the site condition. Increasing depth of foundation Draining the soil Compacting the soil Confining the soil Replacing the poor soil Using grouting material Stabilizing the soil with chemicals 1. Increasing Depth of Foundation … Read more
Classification Based on Degree of Weathering of Rock Mass Rocks can be classified on the basis of its degree of wreathing. These type of rock classification gives the engineer qualitative idea of rock mass. This type of classification is generally done on site and only by a through visual inspection rocks can be classified. While … Read more
Rocks can be classified on site, on the basis of its physical appearance. By making a through visual inspection we can ascertain the engineering properties of rocks. Field classification of rocks gives us logical insight about the suitability of rocks for engineering purpose. This type of classification is known as geological or lithological classification of … Read more
Depth of Soil Exploration Exploration, in general, should be carried out to a depth up to which the increase in pressure due to structural loading is likely to cause perceptible settlement or shear failure of foundation. This depth is known as depth of exploration, which depends upon the following factors. Type of structure Load on … Read more
The knowledge about the site forms a vital role in the safe and economical development of a site. A thorough investigation of the site is an essential preliminary to the construction of any civil engineering works. Objectives of Site Investigation Work To access the general suitability of the site. To achieve safe and economical design … Read more
Prior to construction of a structure, soil investigation is done in order to get the idea of subsurface condition. The scope of a soils investigation is generally depends on many factor, such as Type, size & importance of the structure The client Engineer’s familiarity with the soils at site Local building code Economy If an … Read more
On Site Identification of Silt & Clay The distinction between silt & clay cannot be based on particle size because the significant physical properties of the two materials are related only indirectly to the size of particles. Furthermore, since both are microscopic, physical properties other than particle size must be used as criteria for field … Read more
