【摘要】：钢筋混凝土水池是石化行业常见的构筑物。当水池承受地下水浮力时,水池需要进行整体和局部抗浮验算。对于多格水池和池内立柱水池,水池规范给出了局部抗浮计算公式。经发现,水池规范给出的验算要求较适用于双向设置伸缩缝的水池。而对于不设伸缩缝或只设置单向伸缩缝的钢筋混凝土水池,如果用该公式验算,往往会过于保守,造成材料浪费。分析了水池局部抗浮的含义,明确之后通过对3个算例进行有限元计算分析,展示了如何对水池进行局部抗浮稳定性验算。并且结合工程实例,分析了局部抗浮稳定性不足的情况。
[Abstract]:Reinforced concrete pool is a common structure in petrochemical industry. When the pool is subjected to the buoyancy of groundwater, the whole and local anti-floating calculation is needed. The local anti-floating formula is given for the multi-grid tank and the column tank in the tank. It is found that the checking calculation requirements given in the water pool code are more suitable for the pool with two-way expansion joints. However, for the reinforced concrete pool without expansion joint or unidirectional expansion joint, if the formula is used to check calculation, it will be too conservative and lead to material waste. The meaning of local anti-floating of water pool is analyzed, and then through the finite element analysis of three examples, it is shown how to check the local anti-floating stability of the pool. Combined with an engineering example, the insufficient local anti-floating stability is analyzed.
