挡土桩前夯实填土主动土压

ACTIVE EARTH PRESSURE OF COMPACTION EARTH BEFORE THE RETAINING PILES

结合工程实例,论述深基坑挡土桩与地下室外墙连成一体共同分担侧向土压力。充分利用挡土桩的首先挡土作用,大量减少外墙上的土压力。提出计算方法与简易可行的构造措施,使得挡土桩这一临时性结构达到永久性要求。

The article treats of the retaining piles of deep foundation pit and the ecto-concrete wall of basement absorb sideways earth pressure together with engineering examples.It exploits the retaining earth of the retaining piles at beginning adequately,and freely reduces earth pressure on the ecto-concrete wall of basement.The article brings up calculation method and easy detailing steppes that makes retaining piles which have been extraordinary frame to fulfill permanent demand.
