摘要
采用模拟盾构推进过程的方法,对土的工程性质和盾构尺寸对盾构姿态的影响进行数值分析.通过分析得出了盾构单位距离角度的变化与地层基床系数和盾构尺寸之间的关系,为盾构姿态的控制提供理论依据,并为建立盾构运动过程的数学模型打下基础.
Among all the factors that take effect on this process, the dimension of the shield tunnelling machine and the engineering characteristic of soil are the two main factors of great importance. Under this precondition, a numerical analysis was conducted to estimate the movement of a shield tunnelling machine. The analysis simulated the process of direction change and forward movement. Furthermore, the relation between the direction change and the two factors mentioned above was revealed.
