含水量和压实度对黏性土地基承载力的影响试验研究
Experimental study on influence of clayfoundation bearing capacity by water content and compaction degree
摘要
Abstract
Water content w and compaction degree K are two key factors which affect the bearing capacity of clay - foundation. Through plate load tests and shear strength tests under conditions of different compaction degree, the relation data between compacting factor and clay - foundation bearing capacity was induced firstly. Then, influence of the water content on clay - foundation bearing capacity was investigated by analyzing the changes of soil internal friction angle ρ and cohesion c with the water content changing. At last, a revise method considering water content was proposed based on calculating of clay - foundation bearing capacity by Hansen formula.关键词
