摘要
对地下隧道衬砌结构内力计算的荷载结构法和地层结构法进行了比较，荷载结构法尚不能充分考虑结构与围岩的共同作用，地层结构法中尚不能准确确定多少围岩压力被释放。综合两种方法的优点，提出了一种能考虑共同作用的荷载结构简化模型，并进行了算例比较，通过算例计算表明文中提出的简化方法可行。
A comparison analysis of two traditional design methods of underground tunnel linings was carried out. A new load-structure simplified model based on FEM was proposed in this paper. Through a series of case studies, the applicability of the proposed method was clearly exhibited.
