楼板上砌筑隔墙的可能性分析

长期以来,人们对能否在楼板上直接砌筑隔墙始终持怀疑态度,按现行计算方法,楼板重量、隔墙砌体重和楼板上的使用荷载均由楼板承受,其总和已超过楼板的承载能力.造成楼板的挠度和裂缝超过容许值。因此,目前大量的设计都采用在墙下设置隔墙梁来承受墙体荷载,这样给建筑物的施工、使用都带来了很多不便,而在另一方面,目前确有个别建设工程采用了直接砌筑隔墙于楼板上的作法,若按常规方法计算存在问题。

Geoid Deformation and Elevation Influence Caused by Building Loading

The paper studies the ground vertical deformation and the geoid undulation caused by loading of neighboring buildings, based on the loading tides theory. The influence on elevation is also considered. The results show that the ground vertical deformation and the geoid undulation both reach millimeter magnitude. Therefore, it is obvious that the building loading significantly affects the precise engineering surveying, and it must be seriously considered in application.
