| 摘 要： | 以上海复兴东路大型越江盾构隧道为工程背景。通过建立适合工程结构及工程地质特点的弹性地基模型，在充分考虑隧道结构荷载作用特点、地下水的影响及隧道下部土体反力特性的基础上，推导出了隧道纵向位移的解析表达式，并采用基于土体反力系数的迭代解析方法，计算了部分南线隧道各管片纵向位移值，所得结果与实测结果基本吻合。

| Abstract: | This paper is based on the project of the huge shield tunnel a cross the Huangpu River, linking East Fuxing Road in Shanghai. By establishing an elastic foundation model which is adaptive to structural and geological conditions, this paper gives the resolution of the vertical displacement of the tunnel, adequately considering the character istics of the load on the tunnel, the influence of ground water and the reaction of the soil under the tunnel. As the south tunnel of the project is concerned, this paper calculates the vertical displacement of part of the duct pieces using the escalator method considering the reaction of the foundation under the tunnel. It shows that the calculated values approximately accord with the measured ones. |
