Role of Design Engineer in Geotechnical Investigations
Structural Design Engineer play an important role not only in making a structure safe structurally, but also by ensuring that the site where the construction has to be carried out is safe for the given structure. It becomes very much ...
Soil Classification in Excavation for Measurement and Payment
There are three types of soil classification in excavation for measurement and payment. Rate of each soil types differs based on depth of excavation.
Soil Identification- Approximate Field Procedure
Identification of soil is the first and most important step in soil investigation for engineering works. It is the determination of soil-type through which crucial information about the soil properties can be obtained. Approximate field procedure is a technique by ...
Dry Density of Soil by Core Cutter Method for Soil Compaction
Dry Density of Soil by Core Cutter Method Cylindrical core cutters of 130mm long and 100mm diameter are used for testing the in-situ compaction of cohesive and clay soils placed as fill. By using core cutter method, bulk density of ...
Selection of Foundations Based on Different Types of Soil
Commonly, the selection of foundation type for a given structure is controlled by number of factors for example soil type, past site usage, adjacent construction, size of development process, limitations. Among these factors, types of soil play significant role, that ...
BEARING CAPACITY OF COHESIVE SOILS
Bearing capacity of cohesive soils The ultimate bearing capacity of saturated cohesive soils (clay and silt) with low permeability is most critical immediately after construction, before the excess porewater pressure has had time to dissipate i.e. undrained conditions. As time ...
Types of Shear Failure of Foundation on Soils
Types of shear failure of foundation soils Depending on the stiffness of foundation soil and depth of foundation, the following are the modes of shear failure experienced by the foundation soil. General shear failure (Fig.1(a)) Local shear failure (Fig.1(b)) Punching ...
