摘　　要：通过系统研究岩石隧道 ,尤其是偏压隧道的围岩压力确定方法 ,及其结构计算方法 ,能够在施工过程中对隧道衬砌结构进行动态分析 ,及时调整隧道施工参数 ,达到最佳的效果。文中采用规范推荐方法确定反分析的初始参数 ,采用可变容差的单纯形法进行荷载及地层参数的反分析 ,然后利用反演参数对衬砌内力进行正分析 。The methods to determine the earth pressure and calculate lining structure of rock tunnel are studied, especially for uneven pressure tunnels, by which the tunnel lining can be dynamically analyzed during the construction stages. The construction parameters can be adjusted in time to achieve the best economic results. The recommended methods in regulations are used to determine the starting parameters; the back analysis is carried out adopting the simplex method of changeable tolerance for analysis of load and stratum parameters and the back analysis parameters are used to analyze the internal force of the tunnel lining for guiding the determination of lining parameters.
