跨海隧道深基坑穿越临海断裂带处理方案优化

摘要:

本文以深圳前海某跨海隧道深基坑穿越临海断裂带项目为例，通过现场勘察、数值模拟分析以及降水试验，将采用断裂带帷幕注浆的原设计方案优化为仅采取降水处理断裂带，实施效果良好，可为后续类似工程提供借鉴经验。

Abstract:

This paper takes the deep foundation pit of a cross-sea tunnel in Qianhai, Shenzhen as an example. Through on-site investigation, numerical simulation analysis and precipitation test, the original design scheme of curtain grouting with fracture zone is optimized to adopting precipitation treatment for fracture zone only. The implementation effect is good, which provides reference experience for follow-up similar projects.
