Study on Application Effect of 3D Sonar Seepage Detection Technology in Contiguous Bored Pile Wall
Using the 3D sonar seepage detection technology,through the test holes embedded in and outside the foundation pit structure in advance,the seepage test before excavation is carried out.The two tests of different dewatering depths are compared and analyzed,and the seepage velocity,flow direction within the test range is provided.The results show that this technology has been successfully applied to the saturated soft soil foundation with high water level in Shanghai.Different precipitation depths have great influence on the test results but the leakage points are determined.Experience needs to be accumulated in the future to provide reference for the further promotion and application of this method in Shanghai.
