摘要
本文基于地下水资源开采中机井抽水所引起的土层渗透破坏的实例──地下孔洞问题，介绍对其软弱孔洞地基进行有效加固的方法及辅以基础、上部结构措施的具体做法；并探讨了端夯扩沉管灌注桩的扩大端直径和承动力计算公式、计算参数。
In underground water resource development, using well sump type pumping can cause underground cave-soil piping seepage failure of some soil stratum. In this paper,the method of ground improvement using rammedbulb piles with structural remedies in the foundation and superstructure is presented. At the same time,the diameterof pile bulb and bearig capacity of rammed bulb pile are discussed.
