| 摘 要： | 高速公路的某些地段，土层变形较大，变形历时过长，必须进行路基处理以满足设计要求。在大量现场试验和监测结果的基础,皮肤软土地基变形机理的分析，提出并采用排水固结法的地基处理方案，设计了加压系统和排水系统。加压系统中的第一级荷载和排水井径计算的正确与否是该方法能否成功的关键。

| Abstract: | In some section of freeways, the soil layer existed a large deformation and the deformation is developed for a long time. Treatment for freeways foundation is required to satisfy the demand of design, the method of drainage and consolidation to treat the soil foundation has been used in this paper on the basis of a large amount of field test and monitoring result, still the analysis of the deformation mechanism. The system of drainage and loading is designed; the key for this method is whether the calculation result for the first step loading and the well diameter of the drainage system correct or not. |
