摘要
SMW工法是一种新型施工技术,能够明显降低工程造价,提高支护能力,缩短工期。该文以东南沿海某软土地区的基坑支护工程为例,对SMW工法的应用效果进行探讨分析。该工程的支护方案主要为"SMW工法桩+坑底加固+竖向斜撑",先对基坑支护工程周围的环境、地质和水文条件进行分析,再设计不同的基坑支护方案,通过实际的基坑支护施工应用,分析SMW工法的应用效果,期望为大面积软土基坑支护设计工作提供有益的参考。
The SMW construction method is a new construction technology,which can significantly reduce the project cost,improve the support capacity and shorten the construction period.Taking the foundation pit support project in a soft soil area in the southeast coast for example,this paper discusses the application effect of SMW construction method.The support scheme of the project is mainly“SMW construction method pile+pit bottom reinforcement+vertical diagonal bracing”.Firstly,the environmental,geological and hydrological conditions around the foundation pit support project are analyzed,and then the different foundation pit support schemes are designed.Through the actual foundation pit support construction application,the application effect of SMW construction method is analyzed,and it expectes to provide beneficial reference for the design of large-area soft soil foundation pit support.
