摘　　要：为了提高支护结构的稳定性和安全性,针对复杂地基软土深基坑支护施工技术和施工质量控制展开探究,布置了用于验证结构安全性的监测方案。研究结果表明,随机抽取的围护桩最大水平位移为6.064 mm,支护结构的整体变形处于允许范围内。基坑外的土体变形较小,最大沉降累积量仅0.427 mm,结构的服役性与安全性较好。In order to improve the stability and safety of the supporting structure,the research explores the construction technology and construction quality control of the deep foundation pit supporting in soft soil on complex foundation,and arranges a monitoring scheme for verifying the safety of the structure.The results show that the maximum horizontal displacement of the pile randomly selected is 6.064 mm,the overall deformation of the supporting structure is in a allowed range.The soil deformation outside the foundation pit is small,and the maximum settlement accumulation is only 0.427 mm,so the structure has good serviceability and safety.
