摘要: 基于厦门某临海项目的基坑工程实践，介绍了复杂砂土层中的基坑采用的隔水措施。该项目除分布有巨厚砂层外，地下障碍物众多，设计采用冲孔咬合桩作为止水帷幕，大部分区域隔水效果良好，但局部区域出现渗漏现象。本项目为今后类似项目提供了一定的借鉴经验。

Abstract: Based on a project close to sea in Xiamen, the common measures of waterproof curtain are introduced in deep excavation engineering. Under thick sandy layers and underground obstacles, the geological conditions of this project are quite complex, and the interlocking cast-in-situ piles are used. They work well except partial seepage. Experience in the project can be referred for the similar projects.
