轨道交通车站砌体内隔墙高厚比问题分析

Analysis of Height-thickness Ratio of Inner Partition Walls in Masonry of Rail Transit Stations

结合现行的建筑抗震设计规范及砌体结构设计规范,通过对轨道交通车站砌体内隔墙高厚比(墙体稳定性)分析,初步将内隔墙高度进行稳定性安全分区,明确内隔墙各区段高度的安全性与墙体厚度的关系。在给定墙体厚度情况下,墙体高度不大于安全高度时,均满足规范对墙体高厚比的要求;并给出当需设置超高内隔墙时应采用的内隔墙设置形式。

Combining with the current building seismic design code and masonry structure design code,through the analysis of the height-thickness ratio(wall stability)of the masonry inner partition wall in the rail transit station,and initially dividing the inner partition wall height into different stable and safe partition,clarifying the relationship between the safety of each section of the inner partition wall and the wall thickness.When the wall height is not greater than the safe height under the given wall thickness,all meeting the requirements of the code for the wall height-thickness ratio.The internal partition wall setting form that should be adopted when super-high inner partition wall required are also provided.
