摘要
结合珠海港某典型基坑支护工程实例,分析了复杂地质条件下应用SMW工法的工艺技术要求,根据基坑开挖过程及后期现场监测结果,探讨了软弱土层中基坑侧壁型钢水泥搅拌桩的位移变化以及基坑外侧水位变化规律,并据此提出了该工况下基坑侧壁的变形速率报警经验值,从而为类似基坑支护工程提供参考价值。
Based on a typical project of foundation pit supporting in Zhuhai port, this paper analyzes the technological requirements of SMW method under complicated geological conditions, discusses the lateral displacement of steel cement treated column and groundwater level changes in soft soil-layers according to monitoring results during and after the excavation, and proposes accordingly the alarming value of wall deformation rate in experience under the condition, which can provide valuable reference for similar excavation works.
