某厂区地面塌陷区与地下水渗流路径综合调查与分析

Comprehensive investigation and analysis of ground collapse area and groundwater seepage path in a factory area

某厂区发生严重的地面塌陷,为了塌陷修复及确保厂区道路正常安全使用,本文采用了探地雷达、地震映像法等综合物探方法以及CCTV检测、示踪试验、盐度测试、孔内摄像等检测测试方法探查塌陷区周边空洞和地下水渗流路径,并给出了塌陷修复建议。塌陷修复后采用探地雷达法和示踪试验检测了修复效果,检测结果表明塌陷修复后地下水不再发生渗漏。本文的探查方法和技术路线对类似道路空洞和地下水渗流路径探测以及地面塌陷的预防及修复具有一定的参考意义。

A serious ground collapse occurred in a factory area. In order to repair the collapse and ensure the safe use of the roads in the plant area,the comprehensive geophysical prospecting methods such as ground penetrating radar,seismic imaging method,CCTV detection,tracer test,salinity test,borehole camera detection and other detection and testing methods were used to explore the surrounding cavity and groundwater seepage path of the collapse area,and then the remedial suggestions for the collapse were proposed. After the collapse was repaired,GPR method and tracer test were used to detect the effect of restoration. The results show that there is no leakage in the ground after the collapse repair. The exploration method and technical route in this paper could be referred for the similar road cavity and groundwater seepage path detection and ground collapse prevention and restoration projects.
