摘　　要：为搞清楚水池顶板开大洞的加强措施以及合理的开洞方式,本文结合半地下污水处理厂工程实例,探讨地下水池顶板几种不同开洞方式,对上部结构以及结构整体抗震性能的影响。主要分析以下三种开洞方式,在洞口的两侧竖向构件之间拉梁,在拉梁的同时设置一定宽度的楼板,以及完全开敞不设梁板。通过定量分析几个考查指标,提出大洞口的合理处置方式,供类似的项目参考。To understand the appropriate methods for opening holes in the roof of a water tank,this paper discussed the effects of various hole-opening methods on the upper structure based on an example of semi-underground sewage treatment plant.Three hole-opening methods were analyzed:set up beams between the vertical members,set up beams and plates on the floor,and completely open the hole.Several inspection indicators were analyzed quantitatively,and a reasonable treatment method was proposed to the similar large hole.
