| 摘 要： | 采用荷载-结构法计算双圆隧道衬砌结构内力。衬砌结构与周围土体的相互作用通过设置在衬砌全环的外法向链杆来体现。通过程序的迭代计算,合理区分衬砌结构的抗力区、脱离区范围。通过分析可知,左右平行以及上下重叠双圆盾构衬砌结构的抗力区范围明显不同,说明不同型式的衬砌结构与岩土的相互作用关系有很大差异。双圆盾构的中墙所受轴力较大,是整个衬砌结构受力的关键部位。双圆盾构衬砌轴力分布较均匀,且剪力和弯矩值较小,是较为合理的衬砌结构型式。

| Abstract: | This paper calculates internal force of DOT shield tunnel lining with load-structure method.The interaction between lining structure and the surrounding soil mass is embodied by external normal linkage set in lining ring.Through iterative calculation,resistance area and separation area of lining structure can be divided reasonably.It can be seen from analysis that resistance range of parallel and vertical DOT shield lining structure is obviously different,which indicates that the interaction between differe... |
