摘要
为解决安康机场迁建工程膨胀土地基问题,运用普通强夯、强夯置换、沉管挤密砂石桩3种工艺改良膨胀土地基,通过对比分析浅层平板载荷试验、重型动力触探试验、室内土工试验得到的各项指标,指出强夯置换工艺更适合安康机场的地基处理。
In order to solve the problem o f expansive soil foundation treatment in the construction o f Ankang Airport,common dynamic compaction,dynamic compaction replacement and pipe sinking compacted gravel pile are used to improve expansive soil foundation.By comparing and analyzing the indexes of shallow plate load test,dynamic penetration test and indoor soil test,it is found that dynamic compaction replacement is suitable for the foundation treatment o f Ankang Airport.
