针对近几年在设计工作中发现的新问题,如高层住宅建筑中管道井尺寸设计不合理导致后期维修困难;住宅卫生间因采用同层排水而导致回填层过高,减小了卫生间的净高;建筑物共用大底盘地下室的项目,不合理的地下室顶板上覆土的高度,造成地下室顶板负荷偏大,增加了结构造价等进行分析、探讨,并提出解决方法。 In view of the new problems found in the design work in recent years, such as the unreasonable design of pipeline wells in high-rise residential buildings, difficulties in post-maintenance are caused; the height of backfill layer in residential toilets is too high due to drainage at the same floor, reducing the net height of the toilets ; Projects sharing large chassis basement of the project, unreasonable basement roof soil overburden, causing the basement roof load is too large, an increase of structural cost analysis, discussion, and propose solutions.
