摘要
本文同时考虑土体侧向、竖向变形和土粒流失,导出了抗液化振冲挤密桩间距的计算公式。将该式用于实例计算并与现有计算方法进行对比,发现:不考虑地面下沉和土粒流失时,所得结果有时偏大,有时偏小;仅考虑地面下沉时,所得结果偏大。本文方法同时考虑地面下沉和土粒流失,与实际情况相符,所得结果合理。
Considering both the lateral and vertical deformation of soil mass and washing away of soil grain, this paper derives the calculating formula of the spacing of the vibroflotation compacted piles for anti-liquefaction purposes. Using this formulain actual calculation and comparing with present metkods, the authors find that when not considering the ground subsidence and the washing away of the soil grain, the results obtained sometimes too large, and sometimes too small. When only considering the ground subsidence, the results being too large. In this paper, the ground subsidence and washing away of soil grain arc considered simultaneously, this conforms With the actual conditions, and the results obtained are resonable.
