摘要
利用常规和非常规载荷试验,对客运专线红黏土地基的9个工点进行载荷试验,获得了这9个工点的红黏土的极限荷载及相应的沉降量、基本承载力、变形模量、基准基床系数和p-s曲线,p-t曲线,为客运专线无碴轨道红黏土地基的设计提供了设计参数。
Using conventional and the non-conventional load test,the load test was made to nine work spots of the railway line for passenger traffic line from Wuhan to Guangzhon red clay ground.The following parameters were obtained： ultimate load and the corresponding settlement,the basic bearing capacity,modulus of deformation,datum foundation-bed coefficient and the p-s curve,the p-t curve of these nine work spots of the red clay,which provide the design parameter for the red clay sector design of the railway line for passenger traffic from Wuhan to Guangzhou.
