What is End Bearing Pile? Selection, Uses, and Advantages
End bearing piles, which is also known as point-bearing piles, are used to transfer superstructure load through low bearing capacity soil to a strong stratum such as rock or very dense sand and gravel. They infer most of their load-carrying ...
Dynamic Compaction: Advantages, Purposes, and Uses
Dynamic compaction is an efficient and cost-effective soil improvement technique that uses the dynamic effect of high energy impacts to densify weak soil. The dynamic effect is generated by dropping a static weight (15-40 tones) from a defined height (10-30 ...
Continuous Flight Auger Piles: Constructions, and Applications
Continuous flight auger piles is a type of drilled foundation. It is also known as augercast piles, augered cast-in-place piles (ACIP), auger-pressure grout piles, drilled displacement piles and screw piles.
Determination of Dry Density of Soil by Water Displacement Method
Water displacement test method is used to determine the dry density of soil. It is suitable for evaluating in-place dry density of cohesive soil due to the nature of specimen required. The soil sample should be trimmed to obtain a ...
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 ...
What are the Compressibility and Consolidation of Soil?
The compressibility of soil is defined as the capability of soil to decrease its volume under mechanical loads, whereas the consolidation is the compression of saturated soil under steady pressure and it is occurred as a result of water expulsion ...
