拥有湿陷性地基的砖混结构多层建筑物,若不采取一定的地基加固措施,就会出现长期沉降.为了防止事故的发生,可在建筑物四周开挖探井,然后用水泥土回填夯实(打灰土挤密桩),以限制土体的侧向位移,在竖向结构呈现拱形时进行卸载.采用这种方法进行加固,最终可以达到限制沉降的目的. If a masonry-concrete multi-storey building with collapsible foundation is not constructed, some long-term settlement will occur if some foundation reinforcement measures are not taken. In order to prevent the occurrence of an accident, excavation of exploration wells can be carried out around the building and then compaction Dust-soil compaction piles) to limit the lateral displacement of the soil, unloading when the vertical structure is arched, and the method of strengthening can eventually achieve the purpose of limiting the settlement.
