通过对北京德胜置业大厦高层主楼与地下车库底板沉降的跟踪观测,说明尽管高层建筑深基础基底与周边的地下车库或人防相连,主楼与裙楼或地下结构之间荷载差异较大,且其基础之间互相影响,差异沉降的控制难度较大,但根据各建筑物特点及其地基土层的工程特性采用天然地基和复合地基联合处理方式是可以将差异沉降控制在一定的范围之内的。
Through the follow-up observation of the subsidence of the main building and the underground garage of Beijing Desheng Real Estate Building, it shows that although the basement of the deep foundation of the high-rise building is connected with the surrounding underground garage or civil air defense, the load difference between the main building and the podium or the underground structure is large, However, according to the characteristics of each building and the engineering characteristics of its foundation soil, the combined treatment of natural foundation and composite foundation can control the differential settlement within a certain range .
