摘要:
针对既有地下结构形成的有限区域,研究盾构隧道施工引起土体位移的解析计算方法.根据有限区域盾构隧道施工引起土体位移的分布特征,从有限区域土体位移分布基本特征出发,基于半无限空间盾构隧道土体位移解析解,通过引入广义土体损失和应力边界条件,推导得到一种可以计算有限区域盾构隧道土体位移的解析计算方法,并通过一则工程实例对该方法的有效性进行验证.计算结果表明,有限区域盾构隧道土体位移小于半无限空间盾构隧道土体位移,但两种情况下的土体位移分布形状基本相同.对于有限区域盾构隧道土体位移,和半无限空间解析解相比,本文解析计算方法得出的结果更接近工程实测数据,对计算有限区域盾构隧道土体位移问题更有效
Abstract:
This paper presents an analytic solution for calculating soil displacement induced by shield tunneling in finite soil which is limited by underground structures. Given the basic characteristics of soil displacement around shield tunnel in finite soils, an analytic calculation method for soil displacement in finite soil is obtained based on the analytic solution in semi-infinite soil, considering generalized ground loss and stress boundary condition. Then the effectiveness of the proposed method is evaluated by a realistic project. It proves that the soil displacement in finite soil is smaller than that in semi-infinite soil, while the distribution law of soil displacement in the two conditions is similar. The calculation results show that the outcome of the suggested method is closer to monitoring data compared with that of the method for semi-infinite soil. The proposed method in this paper has the advantages to calculate soil displacement induced by shield tunneling in finite soil
