我单位在1980年自行设计、施工的六层住宅楼工程,采取了楔形灰土桩的办法加固了地基。经过几年来对该建筑物的观察,没有发现地基下沉或墙身变动的情况。这个工程的地基没有经过钻探,是参照附近地区的地质资料,按15吨/米~2设计的。承重横墙的地槽宽度为1.80米。非承 The six-story residential building project that our company designed and constructed on its own in 1980 adopted wedge-shaped ash piles to reinforce the foundation. After several years of observation of the building, no ground sinking or wall changes have been found. The foundation of this project was not drilled. It was designed with reference to the geological data of the surrounding area and was 15 tons/meter~2. The groove width of the load-bearing cross wall is 1.80 meters. Unsupported
