Bearing Behavior Study of Rammed Cement-Soil Pile Compounded Foundation in Collapsible Loess

Abstract:

The rammed cement-soil pile compounded foundation is widely used in collapsible loess of northwest China. There are many factors influencing the bearing capacity of compounded foundation. The calculation result with empirical formula are usually not accurate. The influence factors on bearing capacity of compounded foundation are analyzed with finite element method based on the static load results. The result show that pile body elastic modulus has little effect on the bearing capacity of compounded foundation. This is quite different from bearing behavior of single pile. However, the soil parameters, such as soil elastic modulus, soil internal friction angle and soil cohesion have significant impact on compounded foundation bearing capacity.
