摘要
钻孔压浆桩作为一种新的基础形式,在其它地区已经成为一种比较成熟的技术,但在黑河地区特别在圆砾石地层中还没有成功的经验,在钻进成孔过程中能否成孔,是否坍塌,承载力能提高多少一直是人们所关心的问题,加之以前有过不成功的钻孔桩,引进此项技术的难度较大,直到2001年黑河海关办公楼采用此种基础并获得成功,钻孔压浆桩才在黑河得以推广。
Bored mudjack pile is a new foundation form that is widely used. But it： is not successfully used in pudding stone area of Heihe city. It is difficult to import this technique for the problems such as drilling hole, sloughing, bearing capacity. It is widely spread after it is used in customs ottice building of Heihe city.
