中文摘要：
分析了深部地下工程围岩与结构的相互作用原理，提出了极限状态方程建立准则，然后按照新奥法原理给出最小荷载的估算公式．在分析衬砌力学传递机理基础上揭示了衬砌变形协调的3种基本类型，推导了在不同协调情况下结构实际抗力的计算公式，探讨了极限状态方程的建立方法．根据结构参数和状态函数的复杂性，研究了统计矩方法估算稳定可靠性概率的实用性．由此构成了该类隧道结构稳定可靠性估计的完整方法．并采用该方法分析了某隧道结构的稳定可靠度，验证了其有效性．
英文摘要：
Firstly, the interaction principle between surrounding rock and supporting structure for deep un- derground engineering was studied, and a rule of establishing limit state equation was put forward. The estimation formula of the least load was protxased according to NATM. Three basic types of lining deformation harmo- ny were revealed based on analysis about lining mechanics. Then the calculation equation for actual resistance of the anchor-shotcrete net structure under various different deformation harmony and the establishing method of limit state equation were educed, Rosenblueth method was introduced to evaluate the stability reliability degree of the tunnel lining structure. A practicable calculation method of the stability reliability degree of the tunnel structure was established. The above method was adopted to analyze the reliability degree of a tunnel structure and its validity was verified.
