摘要
为了研究水平透水层对软基沉降的影响,本文运用二维Biot法对不同埋深透水层的软基沉降进行理论分析。结果表明,含有透水层的软基不但竖向变形、水平位移量小,而且压缩稳定所需的时间短,透水层排水能力对加速土层固结是相当有效,因此计算时必须考虑透水层的影响。
In order to study the effect of horizontal permeable water layers on soft foundation settle- ment, Two Dimensional Blot Theory is used in analyzing permeable water layers of the soft foundation settlement of different depths in this thesis. The results show that the amount of vertical deformation and horizontal displacement of soft foundation with permeable water layers are not only small but also it takes very little time to get its compression stabilized. The drainage capacity of permeable fective to accelerate soil consolidation, so the calculation must take the impact layers into account. water layers is fairly ef of the permeable water
