摘   要 ：利用三維聲納滲流檢測(cè)技術(shù)，通過(guò)事先埋設(shè)在圍護(hù)結(jié)構(gòu)內(nèi)部的測(cè)試孔以及坑外補(bǔ)打的測(cè)試孔 ，對(duì)某項(xiàng)目灌注樁排樁圍護(hù)墻結(jié)構(gòu)進(jìn)行開(kāi)挖前的滲漏測(cè)試，提供了測(cè)試范圍內(nèi)的滲透流速 、流量 、流向等指標(biāo)。并對(duì)兩次不同降水深度情況下的測(cè)試結(jié)果進(jìn)行了對(duì)比分析。結(jié)果表明：該技術(shù)在上海地區(qū)高水位軟土飽和地基中得到了比較成功的應(yīng)用，不同降水深度對(duì)測(cè)試結(jié)果有較大的影響，但均判斷出了滲漏點(diǎn)，后續(xù)仍需積累經(jīng)驗(yàn)，為該種方法在上海地區(qū)的進(jìn)一步推廣應(yīng)用提供參考。

Abstract: 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.

Keywords:contiguous bored pile wall; 3D sonar seepage detection; test hole; seepage test; seepage velocity
