First, the authors computed internal force of shield tunnel's lining of a certain city by using the method of free deformed circular ring, and prove that the influence of soil's lateral force is very big to internal force of tunnel, especial to the bendin

摘要通过采用荷载结构模式中连续的自由变形圆环法，对某城市地铁区间隧道衬砌圆环内力的计算，发现土的侧向抗力、侧土压力值对内力影响很大，特别是对弯矩的影响，这将对工程造价産生很大影响。
