摘要
以某深基坑支护工程为研究背景,介绍该工程的工程地质条件、设计方案及支护结构。结合现场监测资料分析深层搅拌桩和双排桩联合支护条件下的基坑变形和桩体变形,结果表明这种支护形式能很好地控制基坑变形,确保基坑稳定。应用数值模拟软件对基坑关键部位进行模拟分析,揭示了深层搅拌桩和双排桩联合支护结构变形特征及受力机理。
A deep pit supporting engineering was introduced in this paper,the engineering geological conditions of the project,design and support structure was described,and the supporting form is deep mixing pile joint double-row pile.On-site monitoring data was analysed,it shows that this supporting form is valid,the deformation of pit was controlled effectively.Finally,the numerical simulation software was used to analysis the key parts of pit,the mechanism and deformation features of this supporting form was revealed.
