本文论述了薄壁地下连续墙在深基坑支护应用中的设计计算方法、施工工艺、挡土防渗效果和经济效益， 并应用工程监测成果， 对计算进行了验证对比。射水法建造薄壁地下连续墙， 其施工方法简单、施工速度快， 对周边影响小， 是一种安全可靠且造价较低的支护形式。
This article discusses the design and calculation method, construction technology, seepage prevention effect and economic benefit of thin-walled underground continuous wall in deep foundation pit support. The results of engineering monitoring are applied to validate and compare the calculation. Water jet method to build thin-walled underground continuous wall, the construction method is simple, fast construction speed, small impact on the periphery, is a safe and reliable and low cost form of support.
