摘　　要：绍兴地区软土分布范围较广,土层较厚.这种特殊的地质条件不仅会给基坑工程的设计和施工带来一定的困难,还可能导致周边建筑物或地下设施的开裂和沉降,造成巨大的经济损失.本文对绍兴地区软土地基基坑支护设计中常用的支护方案及其适用条件进行了总结.结合一个典型的软土基坑支护实例,详细阐述了在考虑基坑开挖深度、地质情况和周边环境等因素影响时,对基坑支护方案的选择,提出了相应的工程经验,并对当前绍兴地区基坑支护方案设计时普遍存在的需要特别注意的要点进行了总结.本文可为绍兴地区软土地基基坑支护设计提供参考.The soft soil is widely distributed with thick soil layers in Shaoxing.This particular geological condition brings forth some difficulties to the foundation pit design and construction; it also leads to the cracking and settlement of surrounding buildings or underground facilities,thereby causing huge economic losses.In this paper,the commonly used foundation pit support scheme and its applicable conditions are summarized.A typical example of soft soil foundation pit support scheme is presented; with the main factors such as the excavation depth,geological conditions and surrounding environment taken into account,the selection of foundation pit support schemes is described; the corresponding engineering experience is also given; the main points that need special attention in the design of foundation pit supporting scheme in Shaoxing are summarized.This paper can provide reference for foundation pit design of soft soil foundation in Shaoxing.
