输水管道盾构隧道衬砌结构内力计算比较分析

Internal Force Calculation and Analysis of Lining Structure of Water Conveyance Shield Tunnel

盾构隧道衬砌内力计算的方法有多种,但各有优缺点。针对潮河输水管道盾构法隧道衬砌结构,分别采用荷载结构法中考虑土体侧向弹性抗力的匀质圆环修正惯用法和连续介质有限元法进行内力计算。通过比较衬砌管片结构内力和变形分布规律,得到了对设计有参考价值的结论。

There are various calculation methods of shield tunnel lining structure,each with its own advantages and disadvantages.For the Caohe Water Conveyance Shield Tunnel,the modification conventional method of homogeneous elastic ring which takes the side elastic resistance of soil into account,and continuous medium FEM method were used to calculate the internal force of lining structure.Some valuable results are concluded through the comparison of the structural internal forces and deformation and its distribution regularities.
