浅埋塑性流变岩体中的隧洞施工

THE TUNNEL CONSTRUCTION OF THE SHALLOW-BURIED PLASTIC RHEOLOGICAL ROCK MASS

对浅埋塑性流变岩体的特点及适合该岩体的施工方法进行了介绍和分析,并以深圳市某排洪隧洞工程为例,详细介绍了采用"新奥法"进行隧洞施工的施工工艺、工序安排、超前支护、初期支护参数和参数调整过程,希望能为类似工程地质条件下的隧洞施工提供有益的借鉴.

This paper introduced the characteristics of the shallowburied plastic rheological rock mass and the construction method which is suitable for this rock mass.And we took the tunnel a engineering of flood carrying in Shengzen city as a example to introduce the construction technique,procedure arranging,support parameters and its adjusting courser on the New Ao method .It can be referred for the tunnel constuction of analogy geology condition.
