在接近已设基础体基脚处进行地下连续墙的构筑,其中还有些问题尚待解决。其一是沟槽周围土的稳定问题,这是与邻接建筑物安全有着直接关系的问题。其二是与开挖的沟槽长度有关的问题。即,具有某种长度的沟槽虽然在开挖后的一定时间内可以用混凝土充填完,但此时的与邻接建筑物的荷载所产生的影响有关的理论分析,尚处在模糊不清的状况中。在这种状况下,一般 There are still some problems to be solved in the construction of the diaphragm wall near the footing of the foundations. One is the stability of soil around the trenches, which is a problem that is directly related to the safety of the adjacent building. The second is related to the length of the trench being excavated. That is, although trenches of a certain length can be filled with concrete within a certain period of time after excavation, the theoretical analysis on the influence of the load of an adjacent building at this time is still in vagueness In the situation. In this situation, in general
