摘　　要：人工挖孔桩是现代建筑的主要基础类型之一，而涌水和流沙是人工控孔桩施工中最棘手的问题。本文结合具体工程实例用高压旋喷注浆处理涌水和流砂的设计参数和施工方法。实践证明，这是一种行之有效、省时省力的好方法。The artificial hole piles are one of most foundation types in the modern con-struction, The problems on water inflow and soil flow are most troublesome in the con-struction of hole piles dug by man。 Combined with the engineering projects ’ the design pa-rameters and constructing method with the high-pressure rotary grouting was used tosolve the problems on water inflow and soil flow are discus:ed in this paper, The practicehas proved that is a time-and manpower-Saving and effective method.
