水处理构筑物地下池体顶板开洞形式对上部结构抗震作用影响的分析

Influence Analysis of Water Treatment Structure Basement Roof Openings form on the Superstructure Seismic Action

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.
