中文摘要：
采用有限元法建立模型,分析复杂地质条件的马鞍子梁公路特长隧道。依据岩性和初期支护参数,计算锚杆抗拉力系数、围岩抗压力系数、喷层混凝土受力系数及结构安全系数,结果表明,初期支护的结构可靠度系数为1.19,达到稳定性要求,可获得稳定的整体结构。
英文摘要：
Using the finite element method to model, Maanziliang long highway tunnel is analyzed in complex geological conditions. Based on lithology and initial support parameters, we calculate the bolt tensile strength coefficient, the surrounding rock compressive strength coefficient, spray concrete layer compressive strength coefficient and structural safety factors. The results show that the primary support structure of reliability coefficient is 1.19, which meets with the stability requirements to get availability of a stable overall structure.
