| 摘 要： | 地下建筑错层位置处的回填土的密实度直接影响了错层位置处的防水效果和较少层底板的均匀沉降,由于此处回填土工作面往往狭窄,常用做法很难达到规范要求的压实系数。采用细石混凝土砌筑毛石墙的方法回填,可大大改善回填土的密实度,还可加快施工进度,降低工程造价。

| Abstract: | The compactness of backfill out of walls which stand at differ storied underground engineering directly acts on the result of waterproofing of these walls and the uniform settlement of base plate on the backfill.Since this working face is always very long and narrow,the conventional ways have difficulty in attaining the normal compacting factor.Replacing conventional ways with rubble walls,which are masoned with pea gravel concrete can not only upgrade the compactness of backfill,but also shorten the construction period and reduce the construction cost. |
