复杂地质与动水环境的临海深基坑支护设计与监测分析

Design and Monitoring Analysis of Deep Foundation Pit Support in Complex Geological and Hydrodynamic Environments near the Sea

研究聚焦于珠海市香洲区九洲港码头附近的某临海深基坑工程,旨在解决其复杂地质与动水环境带来的工程挑战。通过详细分析场地的工程地质条件和海洋动力作用,提出了一套地下连续墙、灌注桩结合钢筋混凝土支撑的支护方案。监测结果表明,方案有效控制了基坑的变形,确保了施工期间基坑的稳定性与安全性。研究为类似沿海深基坑工程的设计和施工提供了实践指导和参考价值。

This study focuses on the coastal foundation pit project near the Jiuzhou Port Terminal in Xiangzhou District,Zhuhai City,aiming to address the engineering challenges posed by complex geological conditions and the dynamic marine environment.Through a de‐tailed analysis of the site's engineering geological conditions and marine dynamics,proposes a support scheme combining underground dia‐phragm walls with reinforced concrete supports and bored piles.Monitoring results indicate that this scheme effectively controls the horizontal displacement of the foundation pit support structure,ensuring stability and safety during construction.This study provides practical guidance and reference value for the design and construction of similar coastal foundation pit projects.
