摘　　要：本文的主要目的是研究深立井混凝土井壁的温度应力及温度应力对井壁结构优化设计的重要影响。本文的研究从物理学中的热胀性原理及热传递理论入手,全面考虑了固体力学中的热弹性理论,平面应变问题的求解方法,推论出了求解温度应力的正确的解析公式。所得结果不仅可用于煤矿立井井壁稳定性分析,对深立井井壁结构的优化设计同时具有重要的参考价值。The main purpose is to research temperature stress of the concrete shaft in rock part of deep shaft, and the important influence of the temperature stress to the optimization design of shaft construction. In this paper, author＇ s research starts from the thermal expansivity and thermal transmission theory in physics, then utilizes the thermo elastic theory in mechanics of elastic bodies and the solution of statically indeterminate system in mechanics of materials as well as the interaction principle between soil and elastic body, finally gets the correct thermal stress analysis formulae of shaft-wall. The research result is not only used to the stability analyzes of shaft in mine, but also used as the reference of the optimization design of shaft construction in rock part of deep shaft.
