摘要
本文根据井壁结构模型试验结果,对目前具有代表性的复杂应力状态下的砼强度准则进行了分析和对比,找到了一种比较适合于井壁结构的砼强度准则,从而为井壁结构承载能力的合理计算提供了理论基础.
In the light of the results of the model tests of the shaftlining structure,the concrete strength criterions are analyzed and compared on current representative complex stress state . A concrete strength criterion available for shaftlining structure is proposed. The theoretic basic is therefore supplied for the reasonable designing of the shaftlining structure bearing capacity in this paper.
