海底隧道与横通道交叉部施工力学研究

摘要

通过采用三维数值模拟厦门翔安主隧道与横通道交叉结构的施工过程，得出隧道交叉部的变形、围岩应力及支护受力特征，研究结论为软弱围岩隧道交叉部设计与施工提供指导。%Through the construction process using three-dimensional numerical simulation of Xiamen Xiang＇ an main tunnel and transverse passage-way cross structure, gained the deformation, surrounding rock stress and supporting force characteristics of tunnel intersection, the study conclusion pmvided.-guidance for the design and construction of weak surrounding rock tunnel intersection.
