基于电阻率成像技术的基坑渗漏探测方法
Foundation pit leakage detection method based on electrical resistivity imaging technology
摘要
Abstract
With the continuous development of city construction and development of underground engineering,increasingly large scale,all kinds of super large and deep foundation pit appear constantly,especially in soft soil and groundwater rich,high water level area,due to the leakage problem of the foundation pit engineering,the accidents happen.Pit leakage is a common construction defect of construction waterproof curtain,therefore,it is necessary to detect the leakage situation of the foundation pit supporting system in advance,if it is found that the leakage area is treated and prevented in time.At present,the problem of foundation pit leakage detection is commonly used in domestic and international water level observation in the foundation pit.It is rare to use the geophysical method to detect the leakage in our country.In this paper,the leakage of foundation pit system,variation of groundwater flow around the foundation pit line,to streamline the leaking water seepage line location aggregation,intensive regional seepage resistance,is resulting in leakage of soil around the foundation pit of low resistivity.Based on the resistivity imaging technique,the method for detecting the leakage of the foundation pit by detecting the change of resistivity of soil around foundation pit before and after dewatering is presented.Two engineering examples show that this method can detect the pit leakage detection results of three-dimensional position,detection results objectively and accurately.关键词
