摘　　要：通过对上海郊环(南环段)软土地基处理的现场原位观测资料的综合分析,探讨了排水固结法在高速公路软基处理中的应用效果,并总结了上海地区排水固结预压法处理软土路基的适用条件、最短预压工期、结束预压期的最佳沉降速率等一些规律性的经验。Based on the in-situ measurement data of soft foundation treatment in the suburb circle expressway (South circle section) in Shanghai, this paper studied the application effect of the preloading consolidation method. Some rule experiences of this method in Shanghai are summarized, such as validity limit, the shortest preloading tune, and the optimal settlement rate for preloading terminative time.
