针对于当前桥梁桩基溶洞探测中在桩底利用探地雷达采用环形测线点测方法不能有效指导孔洞开挖,且在判定不良地质体规模上存在主观模糊性的现状。本文提出基于地质编录及探地雷达的桥址区综合地质分析技术,不仅能够结合地表环境及开挖深度进行地层划分,而且可以确定空洞开挖过程中不良地质体的边界问题,给桥址区孔洞开挖提供了地质参考,为安全施工提供了技术支持。
In view of the current bridge piles cave exploration in the bottom of the pile using ground penetrating radar point detection method can not effectively guide the hole excavation, and in determining the size of the poor geological body subjective ambiguity of the status quo. In this paper, based on geological cataloging and ground penetrating radar, the comprehensive geologic analysis of bridge area is proposed. It not only can separate the strata in combination with the surface environment and excavation depth, but also can determine the boundary problem of poor geological body in the process of empty excavation, Hole excavation provides a geological reference, providing technical support for safe construction.
