Determination of In-situ Density of Soil by Water Replacement Method
The water replacement test method is used for the determination of field density of soil and rocks (includes materials that commonly contain particles larger than 75mm) in a test pit based on the ASTM D5030. It is specifically used for ...
What is Uplift Pressure? Effects on Foundations, and Prevention Strategies
Uplift pressure, which is also known as hydrostatic uplift, is an upward pressure applied to a structure that has the potential to raise it relative to its surroundings. It is the condition of greater pore water pressure than the overburden pressure ...
Determination of In-situ Soil Dry Density by Sand Replacement Method
The sand replacement test method is used to determine in situ dry density of soil. The procedures, materials, equipment, and specifications of this test is based on the Indian Standard (IS 2720 part 28). This test is of significant importance ...
What are the Foundation Design Requirements?
There are many design requirements that foundation structure need to met in order to perform its function adequately and serve its purpose. For instance, it should be strong enough to minimize differential settlement and should be able to safely support ...
Variable Head Permeability Test of Soil- Purpose, and Procedures
Variable head permeability test is one of several techniques by which the permeability of soil is determined. It is used to evaluate the permeability of fairly less previous soil. Permeability is the measure of the ability of soil to allow ...
12 Factors Influencing Bearing Capacity of Soils
The bearing capacity of soil is influenced by many factors for instance soil strength, foundation width and depth, soil weight and surcharge, and spacing between foundations. These factors are related to the loads exerted on the soil and considerably affect ...
Factor of Safety for Bearing Capacity of Soils
Factors of safety for bearing capacity is a value which is established based on the type of soil, method of exploration, level of uncertainty in soil, importance of structure and consequences of failure, and likelihood of design load occurrence. So, ...
