半地下式圆形贮液池结构分析

摘要

根据某污水处理工程中一圆形贮液池的设计资料,描述了半地下式圆形贮液池的荷载分布特点.利用弹性力学的方法,推导了沿池壁部分高度分别作用三角形和矩形分布荷载时半地下式圆形贮液池池壁内力的解析表达式,沿池壁全部高度作用三角形或矩形分布荷载时的池壁内力经典计算公式作为特例含于其中.将推导的解析解与通过有限元分析软件ANSYS计算求得的数值解进行了对比,结果表明两者符合较好,从而验证了所推导解析解的正确性.%According to the design data of a circular tank in a sewage disposal project, the load distribution of half-underground circular tank was described. The analytical expressions of internal forces of wall subjected to triangularly and rectangularly distributed load along partial height of wall were separately deduced by the method of elasticity; the classical formulae of internal forces of wall subjected to triangularly or rectangularly distributed load along the whole height of wall were included as the especial case. The comparison between the analytical solution and the numerical one,which was calculated by the finite element analysis software of ANSYS, it shows that the analytical solution agreed well with the numerical one, and thus the correctness of analytical solution was veritied.
