| 摘 要： | 采用MidasGTS软件对深圳丰盛町阳光地下街深基坑工程的排桩支护体系进行了有限元模拟,计算了各种开挖工况下的支护体系受力和变形情况。围绕分步开挖过程中深基坑支护体系与土体应力和变形进行了较深入的研究,通过将数值模拟与现场实测数据进行对比分析,结果表明研究成果和测试数据基本吻合,说明文中研究成果是合理的,起到了施工超前预测、预报的效果,为基坑工程提供了理论依据和指导,有助于提高深基坑设计水平和安全性,并为类似工程积累了宝贵的经验。

| Abstract: | Midas GTS software has carried on the finite element simulation to Shenzhen Sumptuous Chouyou Light Underground Street deep pit excavated for building foundation project's piling supports and protections system,calculated each kind to excavate under the operating mode the supports and protections system stress and the distortion situation. In summary,this thesis has analyzed the response of soils and the behavior of support in the process of excavation by steps. The results acquired by means of numerical si... |
