| 摘 要： | 在市政隧道工程中,联络通道与泵站经常采用合并建造方式,因此在冻结法施工冻土帷幕时一般也需整体考虑,这样就形成了形状异常复杂的冻土帷幕结构。平面应变及解析很难,不易考虑,本文针对这种情况,对某隧道工程中冻结法联络通道及泵站合并建造施工进行了数值分析。主要分析开挖所对冻土帷幕受力与变形的影响以及冻土帷幕内应力与变形的分布情况,并指出帷幕中的最薄弱部位,同时也验证该工程中1.6m冻结帷幕厚度的安全性,对于类似工程施工有一定的指导意义。

| Abstract: | The construction of the connected aisle is always combined with the pump station in metro tunnels.So the frozen soil curtain should be taken into account from a whole point view.Then the frozen soil curtain is of complex shape.It is very difficult to solve this problem using plane stress method and analytical method.In order to solve this problem,influences of the excavation steps on the stresses and deformation of the frozen soil curtain are analyzed,and the weak part of the frozen soil curtain due to stre... |
