| 摘 要： | 杭州某污水处理厂双线圆形管道拟采用顶管隧道施工方案,分别用plaxis软件进行有限元分析和经验法计算得到顶管隧道穿越钱江二桥铁路桥梁引起的地面变形、桩基变形、桩基承载力影响大小数据。结果证明顶管穿越铁路桥,对桥梁影响较小。

| Abstract: | The program of the double-line round pipeline of a sewage treatment plant in Hangzhou is to adopt the scheme of top-tube tunnel. By respectively analyzed by finite element method with praxis software and empirical method, the data such as the deformation of ground and pile foundation, the bearing capacity of pile foundation and so on, which are caused by that the top-tube tunnel crosses through the railway bridge of the 2nd Qiantang River Bridge. The results prove that the top tube crossing through the rail... |
