通过现场试验研究了路堤堆载作用下低强度桩复合地基的桩土应力比。将路堤堆载作用下低强度桩复合地基的桩土应力比与低强度桩单桩复合地基载荷试验中得到的桩土应力比进行对比,探讨了低强度桩复合地基在不同性质荷载作用下的桩土应力比存在差异的原因。
The pile-soil stress ratio of low-strength pile composite foundation under embankment load is studied through field tests. The pile-soil stress ratio of low-strength pile composite foundation under embankment load is compared with the pile-soil stress ratio obtained from the load test of low-strength pile single-pile composite foundation, and the effects of different kinds of loads on the low- Reasons for the difference in pile-soil stress ratio.
