考虑到黄土地基的承载力,12～16层建筑物的浅基础通常采用满堂板式基础,基础下面的压缩层厚度很大(20～24m)。在这种情况下,采用基槽预浸水的方法,只消除基土在自重作用下的沉陷,是满足不了要求的。在建筑物造成、地基承受到基础传递的荷载之后,一旦出现基土水浸事故,就会产生很大的附加沉陷,在仅由基土自重所产生的沉陷已经完成的地基下部,也是如此。在高层建筑中,从电梯运行和其它公用管网的安全要
Considering the bearing capacity of the loess foundation, the shallow foundation of the 12 to 16-story building is usually a full-fledged plate foundation, and the compression layer below the foundation is very thick (20 to 24m). In this case, using the method of pre-soaking the base tank, only eliminating the subsidence of the foundation soil under the action of its own weight can not meet the requirements. After the building has caused the foundation to withstand the load transmitted by the foundation, once a subsoil flooding accident occurs, a large additional subsidence will occur. This is also true in the lower part of the foundation where the subsidence caused only by the weight of the subsoil has been completed. In high-rise buildings, safety from elevator operations and other public pipe networks
