深基坑支护的增量计算方法研究及其应用
|
摘要
在地质基础条件差,并且载荷变化复杂的大型基坑支护结构变形计算中,增量法计算相对其他计算方法具有明显的优越性。本文采用增量法对苏州地区某项目基坑支护工程在开挖过程中的水平位移分析进行计算整理,通过对比规范说明设计的合理性,并为深基坑开挖施工提出实际指导建议。
The incremental method of retaining structures for deep excavations under the condition of bad geological conditions and complex loads has the obvious superiority compared with other computational method for it. In this paper, a certain project in Suzhou district with complex deep excavation is studied with incremental method, the results shows the method is correct and reasonable according to corresponding design specification. Finally, the calculation process can put forward practical suggestions for deep excavation construction.
