摘要
对土工格栅的功能与工作机理进行了分析,通过在载荷试验中桩顶盒桩间土的位置铺设土工格栅,在土工格栅的上下层埋设土压力盒来了解土工格栅对桩土应力的影响。通过对桩土压力数据进行处理,分析了土工格栅的作用机理与加固效果。
The functions and working mechanism of geogrid are analyzed. Based upon analysis of the earth pressure data acquired by loading test of composite foundation the influences of geogrid on pile-soil stress are studied, In the end the working mechanism and reinforcement effect of geogrid are analyzed.
