非全埋地下室顶板作为结构嵌固部位的探讨

Discussion on partially buried basement acting as fixed place of superstructures

通过对带全埋地下室、带三面填土地下室、仅包含地下室顶板以上楼层三种结构模型进行多遇地震、罕遇地震作用下的计算与分析,探讨了非全埋地下室作为上部结构的嵌固部位的必要性、可能性。最后得出结论:对非全埋地下室采取结构布置方面和承载力设计方面的措施,并进行不同地震水准下的结构计算分析和比较,是可以将其地下室顶板作为上部结构的嵌固部位。

Through the calculation and analysis of three structural models with full buried basement,three side filled basement and only including the floors above the basement roof under frequent and rare earthquakes,the necessity and possibility of partially buried basement as the embedded part of superstructure are discussed.Finally,it is concluded that the partially buried basement roof can be used as the embedded part of the upper structure by taking structural layout and bearing capacity design measures,and analyzing the structural stress and deformation under different seismic levels.
