摘要

依据隧址区工程地质特征，建立通—渝深埋公路隧道1:1实体模型。通过有限元数值模拟，结合量测资料，分析了隧道按全断面法和台阶法动态施工过程围岩-支护结构屈服接近度、位移和应力特征，以及支护结构钢支撑受力、二次衬砌轴力和弯矩特征。结果表明，在相同的地质条件和支护条件下，台阶法较全断面法没有明显的优势，为深埋公路隧道优化设计和施工提供了科学依据。

Abstract

Based on engineering geological features of tunnel setting

a1:1 hypostatic model of Tong-Yu deep buried highway tunnel is built. Combined measuring results

characteristics of yield degree

displacement

stress of surrounding rock-supports structure

as well as steel support force and lining axis force and bending moment of supports structure are analysed when the tunnel adopting full face method and bench method dynamic excavation. The analytical results show that the bench method there isn’t obvious advantage than full face method. The study provides a scientific basis for optimizing design and construction of deep buried highway tunnels.
