用VB编程求解盾构掘进时轴线任意一点处的理论压力值

摘要：本文通过可视化软件VB编写小软件，求解盾构机掘进时轴线任意一点处的理论压力值，以上海轨道交通11号线南段工程10标盾构临港新城站盾构出洞为例，分别选取设计轴线处第57环、118环和148环管片3个点为参考值进行比较，结果表明用编写软件求解的理论值与施工过程中实际设定值基本一致。因此用此软件可以指导盾构机的后期掘进施工，给工程计算带来一定的便利。

Writing software by the VB visualization software to solve the theory pressure of the TBM at any point at the axis

Abstract: Writing software by the VB visualization software to solve the theory pressure of the TBM at any point at the axis. In this paper, take the Shanghai Metro Line 11, the southern section of LinGang City Station for example, select three points at axis(C57, C118 and C148) as the reference value , the results show that the theoretical value solving by using software and actual value got at Construction process are the same basically. Therefore, this software can guide the construction of the late TBM, to bring some facilities for engineers.
