摘　　要：以杨村矿风井-550 m层位三立板井壁接头为研究对象,先对冻结井可缩性井壁接头采用优化理论进行参数设计。然后再通过ANSYS有限元程序对井壁接头进行数值模拟。结果表明,三立板接头的竖向极限承载力和水平极限承载力分别为28、30.8 MPa,且其水平极限承载力远大于外侧恒定水压(5.39 MPa)。有限元程序得出的井壁的尺寸接头方案与优化理论得出的设计方案相比,有限元程序成功将杨村矿风井三立板井壁接头的外立板厚度减薄了10 mm。同时,有限元模拟还表明井壁接头处的弧形板具有抵抗外部竖向荷载的作用。Yangcun mine air shaft-550 m three vertical plate shaft wall joint as the research object,first of all, the optimization theory is used to design the parameters of the extensibility shaft wall joint.Then through the ANSYS finite element program to carry on the numerical simulation to the well wall joint. The results show that the vertical ultimate bearing capacity and the horizontal ultimate bearing capacity of the three vertical plate joint are 28 MPa and 30.8 MPa respectively, and their horizontal ultimate bearing capacity is far greater than the external constant water pressure(5.39 MPa). Compared with the optimization theory, the finite element program successfully reduces the thickness of the outer vertical plate of the three vertical plates of the shaft wall joint by 10 mm. At the same time, the finite element simulation also shows that the arc plate at the joint of shaft wall has the function of resisting the external vertical load.
