摘　　要：为解决大直径塑料检查井在雨季或地下水位较高条件下安装和使用时抗浮力差的问题,提出一种大直径塑料检查井抗浮力结构设计方案。通过对大直径塑料检查井进行受力分析和抗浮力理论分析,采用正交试验法对其进行抗浮结构设计,得到了大直径塑料检查井抗浮力结构最优设计参数组合。利用ANSYS对遴选出的参数组合进行有限元仿真,通过分析不同方案对检查井底部隆起的影响,得出了解决检查井底部隆起问题的最佳方案。In order to solve the problem of poor buoyancy resistance of large diameter plastic inspection wells when they are installed and used in the rainy season or under the condition of high water table,a design scheme of buoyancy resistance structure of large diameter plastic inspection wells is proposed.Through the force analysis and antibuoyancy theoretical analysis of large diameter plastic inspection wells,the anti-buoyancy structure of large diameter plastic inspection wells is designed by the orthogonal test to obtain and the optimal design parameter combination.ANSYS was used to carry out finite element simulation on the selected parameter combinations.The effects of different schemes on the bottom bulge of the inspection well is analyzed to derive the optimal scheme to solve the problem of the bottom bulge of the inspection well.
