摘要：利用鉆孔取芯、聲波透析、結構掃描等多種檢測手段，對缺陷地連墻質量進行評估。在深入分析地連墻缺陷產(chǎn)生原因后，以工期、安全、有效、低成本為原則，提出了“地連墻+H型鋼柱+混凝土內(nèi)支撐”的支護體系;利用RSD基坑支護計算軟件證明了方案的合理性。通過實際開挖，證明了此套支護方案的可行性。

Abstract：This paper uses multiple testing methods such as drill core method， cross-hole sonic logging， structural scanning， etc. to evaluate the quality of defective ground connecting walls. After in-depth analysis of the causes of ground wall defects， based on the principles of construction period， safety， effectiveness， and low cost， the supporting system of “ground wall + H-shaped steel column + concrete internal support” was proposed for the first time. Using RSD foundation pit support calculation software to prove the rationality of the scheme. The actual excavation proves the feasibility of this set of supporting schemes.

Key words：foundation pit support; diaphragm wall; H-shaped steel column; RSD
