摘要
结合昆明某具体工程实例,利用plaxis有限元软件,基于土体HS模型分析"放坡+桩锚"支护下深基坑开挖过程中支护结构的变形及其对临近建筑物的影响。与实际监测结果对比表明:采用的计算模型及参数是合理的,模拟与监测结果具有一定的一致性,可以为昆明地区深基坑开挖影响邻近建筑变形预测提供参考。
The design and practice of a deep excavation with combined forms of step-slope and pile-anchor retaining in kunming was presented. The finite element software Plaxis based on the Hardening Soil model was adopted to analyze the deformation of the retaining structure and its effect on adjacent buildings during the excavation. Contrast the calculation results with the measured data, the calculation model and parameters was proved to be reasonable. The model is suitable to predict the deformation analysis of deep excavation in kunming.
