摘要
该文重点介绍大直径冲孔灌注桩及人工挖孔桩施工过程中，如何解决多层溶洞漏浆、堵漏及灌注处理问题，同时也介绍了抽取地下水对周围建筑物影响的处理措施及保证办法。
The paper stresses to introduce that in the construction process of the large diameter percussion drilling cast-in -place pile and artificial dig-hole pile , how to solve the pulp leakage and blocking up,and the treatment measure at the grouting places of the multilayered karst caves . At the same time, it also introduces the treatment measures and guaranteeing methods for the influence of pumping groundwater on the surrouding buildings.
