设置内衬框架层的地下水池结构设计

Structure Design of Underground Tank with Lining Frame Layer

地下水池结构不断加高加深,其支护和主体结构的内力变形控制越来越困难。通过工程实例,对设置内衬框架层的地下水池结构设计进行了分析研究,探讨了内衬框架层的位置和刚度对支护结构的影响;并对地下水池结构池壁和内衬框架层的结构设计进行了分析研究。研究结果表明,内衬框架层的位置和刚度对主体和支护结构的内力变形均有重要影响,设计时应综合考虑支护结构和内衬框架的内力变形,合理设计其位置和刚度;内衬框架层的结构设计应增加换撑工况的正常使用极限状态设计,且与其他工况进行包络设计。

With the heightening and deepening of the underground tank structure,it is more and more difficult to control the internal force deformation of its support and main structure.Through the engineering example,the structure design of the underground tank with the lining frame layer is analyzed and studied,the influence of the position and stiffness of the lining frame layer on the supporting structure is discussed,and the structure design of the wall and lining frame layer of the underground tank structure is analyzed and studied.The results show that the position and stiffness of the lining frame layer have an important effect on the internal force deformation of the main body and the supporting structure.The internal force deformation of the supporting structure and the lining frame should be considered comprehensively in the design,and its position and stiffness should be designed reasonably.The structural design of the lining frame layer should increase the design of the normal limit state of use in the bracing changing condition,and the envelope design with other working conditions is carried out.
