摘　　要：文章针对新的《混凝土结构设计规范》要求,合理地提出厚壁圆筒结构物在二轴受压和三轴受压下,采用以概率理论为基础的极限状态设计法,用分项系数进行设计,且结合工程设计本身具体因素,给出了混凝土强度提高系数的取值关系。其在深厚表土层冻结法井壁设计过程中,对井筒的施工进度、安全、经济效益都有着重要的指导意义。According to the requirements of a new issued ＂Design Code of Concrete Structure＂, a probability theory as a basic ultimate state design method with subitem coefficient was applied to the design of the thick wall cylinder structure under a biaxial compression and triaxial compression. And in combination with the certain factors of the project design, a value selection relationship on the improved coefficient of the concrete strength was provided. During the design process of the freezing shaft liner in a deep and thick overburden, all above would have important guide significances to the construction schedule, safety and economic benefit of the mine shaft.
