【摘要】 针对立井井壁承受不均匀压力的实际受力条件,采用有限元数值模拟方法,对双层钢板混凝土井壁结构的力学特性进行了分析,基于三轴应力状态下混凝土强度提高系数的有关规定,验证了所设计的双层钢板混凝土井壁结构在不均匀压力作用下满足强度要求,可为类似井壁结构设计提供参考。更多还原

【Abstract】 Aiming at the actual condition that non uniform pressure act on shaft linging,adopting finite element numerical simulation method,mechanical characteristic of twolayer steel plate and concrete shaft lining is researched.Based on pertinent regulations of concrete strength improving coefficient in the state of triaxiality stress,designed twolayer steel plate and concrete shaft lining meet strength need under non uniform pressure.The research findings can provide referrence for similar structure design.更多还原
