摘　　要：为有效提高开设洞口的EPSC格构式混凝土墙在实际工程中的水平承载能力,应用大型有限元分析软件ANSYS建立12个格构式墙体模型,以洞口形式、洞口位置及洞口大小为设计参数,在单调载荷作用下,对其水平承载能力进行分析.研究结果表明:洞口的出现会使EPSC格构式混凝土墙的水平承载能力明显减小,洞口截面积越大,其水平承载能力越低;洞口总截面积相同时洞口数量对墙体的水平承载力影响不大,但洞口数量越多,承载力越低;洞口截面积相同,随洞口位置距离墙体中心距离增大,墙体极限载荷也有所提高.In order to improve the actual project cement polystyrene formwork lattice concrete wall（EPSC） horizontal bearing capacity, this paper used finite element analysis software ANSYS to establish 12 lattice wall model to form the hole with design parameters of the hole position and hole size, and analyzed the horizental bearing capacity of a lattice wall under monotonic loading. The results of study show that opening occurance will significantly reduce the level of the bearing capacity of the wall, the larger opening cross section area, the lower the level of carrying capacity. For openings with the same total cross section area, the quantity of the number of opening has not much effect on horizontal bearing wall; however with the same opening cross section area, the more the hole quantity, the less the horizontal carrying capacity. With the increase of the distance between the hole location and the center of the wall, the wall ultimate capacity is improved.
