摘要: 城市化的快速发展促使城市建设中基坑工程的规模不断加大,复合土钉墙因其安全经济的特点,得到了极大的重视。根据具体工程实例,运用MADIS/GTS对基坑开挖过程进行模拟,得出了不同工况下基坑的位移变形情况,并对普通土钉墙与复合土钉墙的支护效果进行比较,同时对施加不同预应力情况下基坑的变形进行了分析,归纳出相关的结论,可供类似工程参考。Abstract: Rapid urbanization process brings development of large-scale excavation engineering in cities. The application of composite soil-nailing wall has attracted great attention because of its advantages such as security and low price. The displacement deformations of excavations under different working conditions and prestresses are gained, and a comparison of supporting effects between common soil nailing-wall and composite soil-nailing wall is performed through excavation process simulation by means of the software MADIS/GTS according to engineering practices. It may provide reference for similar projects.
