摘要
以带柱水池为分析对象,对水池的局部抗浮采用了手算、有限元计算法。对比计算结果发现:在设计中常用的将支撑结构均匀分摊面积的做法是不合理的,容易造成浪费;局部抗浮安全系数为1.00的手算结果,与有限元计算结果相近,故认为在整体抗浮满足要求的情况下,可适当降低局部抗浮稳定安全系数。
Taken the tank with column as the analysis object, for local anti floating of the pool are calculated by manual calculation and finite element calculation in this paper. According to the compared calculation results, it is found that the support structure share the area equally is unreasonable because it will cause waste;The local anti floating safety factor of 1.00 by manual calculation result is similar to the finite element calculation result. Therefore, it is considered that the safety factor of local anti floating stability can be appropriately reduced when the overall anti floating meets the requirements.
