In this article we will discuss about the laplace equation for determining two-dimensional flow of soil elements. Consider a soil element of infinitesimally small size of dx and dz in X- and Z-directions, respectively, through which the flow is taking place, shown in Fig. 10.8. Consider unit length of the soil element in the Y-direction. Let vx be the velocity [...]
In this article we will discuss about:- 1. Introduction to the Compaction of Soils 2. Definition of Compaction 3. Principle 4. Effect 5. Factors 6. Method. Introduction to the Compaction of Soils: Soil is used as a construction material for constructing embankments and subgrades. Embankments are constructed to raise the ground level above the existing level up to the formation [...]
In situ tests give a more realistic picture of soil properties basically because of two reasons: i. The in situ tests cover a larger area and volume of soil mass than the laboratory tests which are conducted on small-size samples of soil. ii. Several site factors, such as non-homogeneity of soil, groundwater table, moisture content, cracks, fissures existing in the [...]
