大型钢筋混凝土水池分离法与共同作用法计算分析

Calculation and Analysis of Separation Method and Interaction Method for Large Reinforced Concrete Water Tanks

大型钢筋混凝土水池结构多采用有限元计算方法分析,包括分离法与共同作用法。论文对典型水池结构分别采用两种方法进行计算,对计算结果进行对比分析;对影响两种计算方法差异的主要因素地基刚度、水池底板刚度进行了研究,分别取不同的地基压缩模量与底板厚度,对不同模型的计算结果进行分析。得到了基本结论:当地基与底板刚度足够大时,共同作用法的计算结果将趋近于分离法,可以采用分离法对水池结构进行分析;当地基与底板刚度有限时,两种方法计算结果差异较大,建议采用共同作用法或两种方法包络对水池进行计算分析。

Large reinforced concrete water tank structures are usually analyzed by finite element method,Such as separation method and interaction method.Two methods were used to calculate the typical tank structure,and the results were compared and analyzed;the main factors affecting the difference between the two calculation methods-foundation stiffness and tank floor stiffness were studied.Different foundation compression modulus and floor thickness were taken respectively,and the calculation results of different models were analyzed,and the basic conclusions were obtained.When the stiffness of the foundation and the bottom plate is large enough,the results of the interaction method will approach the separation method.The separation method can be used to analyze the tank structure;When the stiffness of the foundation and the bottom plate is limited,the calculation results of the two methods are quite different.It is recommended that.The interaction method or both methods were ased to calculate and analyze the water tank.
