摘要
淤泥质软土由于其天然含水率高、压缩性大、强度低及其地域性差异,基坑开挖风险较大。其支护方案的选择对工程的造价、进度、质量影响明显,甚至成为工程目标能否顺利实现的关键。通过对我国沿海地区淤泥质软土的特点分析,结合工程实践,对常用的基坑支护体系进行综合分析比较,阐明了基坑支护因地制宜的设计施工原则。
Due to the mucky soil＇s high natural moisture content, large compressibility, low strength and other areal discrepancies, the risk of foundation excavation is high. The choice of its retaining method affects obviously the cost, schedule and quality of the project, and even may be the key to the successful achievement of the project＇s objective. Through the analysis of the characteristics of littoral mucky soils, the common retaining and protection systems of foundation excavation in China were comprehensively compared and analyzed in combination with the engineering practices, and the engineering and construction principle of ＂adjusting measures to local conditions＂ was expounded for the retaining and protection of foundation excavation.
