益阳市某建筑，面积800m2，采用扩大基础。A轴、B轴的南端，由于地处边坡，地势空虚，采用阶梯状的块石扩大基础，基础宽700mm.上部工程开工后，发现块石基础砂浆饱满度差，同时设计由5层改为6层，增大了基础荷载，为此在基础块石灌浆的同时，还采用加拉和措梁的加固方案，缩短 A building in Yiyang City, with an area of ​​800m2, adopts an enlarged base. At the southern end of the A and B axes, due to the fact that it is located on a slope, the terrain is emptied, and a stepped block stone is used to expand the foundation. The foundation is 700 mm wide. After the upper engineering is started, the fullness of the stone based mortar is found to be poor, and the design is changed from 5 floors. For the 6th floor, the basic load is increased. For this purpose, in addition to the grouting of the basic block stone, the reinforcement plan of Gallar and Chen Liang is adopted to shorten the foundation load.
