| 摘 要： | 重庆上界高速公路E1合同段所经路线位于重丘区，冲坳沟多。且地表多为水田、鱼塘、藕池，常年积水，沟谷中多为低液限粘土。厚度3～10m不等。粘土多呈可塑状，部分为软塑状，含水量大，孔隙比高，压缩模量小，沉降量大、承载力小，属于软弱地基。高填方路基和部分涵洞位于软基上，设计采用碎石桩进行处理。本文就碎石桩施工工艺、施工控制指标以及施工后效果进行分析与评价。

| Abstract: | Contract E1 of Shang-jie highsway in Chongqing lies in heavy mountain area, in which there are many ditches, paddy fields, and ponders with water. There is lower liquid limit clay in the ditches. The thickness of the clay is from 3 to 10 meters. The clay almost shows as plasticity and some presents as soft plasticity with much water. The clay is of small modulus of compression, large settlement, and little bearing capacity. The clay belongs to soft foundation. High embankments and some culverts have to be built on it, so designers adopt gravel pile to deal with soft foundation. This paper analyzed and estimated the construction process, construction control index and affection of gravel pile. |
