摘要
在石灰岩地区的建筑基础设计为挖孔桩时,需进行桩底岩溶探测。本文介绍了3种可行的桩底探测方法,主要对地质雷达法与地震反射波法两种物探方法的基本原理及具体探测技术进行了介绍,通过对物探方法与传统钻探法进行有效组合可以提高人工挖孔桩桩底探测的效率和准确性。
If the foundation of a construction is designed as digging stack in a limestone terrain, it is necessary to detect solution cavity at the stack base. Three feasible exploration methods are introduced in this paper. The basic principle and exploration technique of reflection seismic method and ground-penetrating radar method are also introduced. With the effective combination of the geophysical method and traditional drilling method effectively, the efficiency and precision of Stack bass exploration can be improved significantly.
