上海浦东国际机场跑道工程软土地基处理方案选择时 ,对排水板堆载预压试验区和强夯加固试验区的系统沉降观测资料进行了对比分析。结果表明,强夯加固后地基的浅部层组压缩性能有明显改善。在软粘土中 ,与天然地基相比 ,设置排水板将使地基沉降明显增大。
At the selection of the soft soil foundation treatment scheme of the runway engineering of Shanghai Pudong International Airport, the sedimentation observation data of the drainage preloading test area and the dynamic compaction test area were contrasted and analyzed. The results show that the compressibility of the shallow layer of the ground after ground consolidation is significantly improved. In soft clay, the setting of drainage boards will significantly increase the settlement of foundations compared to natural foundations.
