摘要
土石坝施工期稳定计算时,需要计算孔隙水压力。对用于土石坝填筑的不透水土体需进行试验研究,以提供施工期的初始孔隙水压力μ0。经对三轴试验、孔隙水压力消散试验及压缩试验所计算得的孔隙水压力μ0参数进行比较,并结合孔隙水压力消散系数CV研究,提出土石坝施工期稳定计算所需的合理建议参数。
The pore-water pressure need to calculate when the stability of the earth-rock dam is calculated during construction.Based on test of the impermeable soil body used filling earth-rock fill dam,the initial pore-water pressure μ0 was obtained.In this paper,the parameters μ0 of the pore-water pressure calculated from the trail test,pore-water pressure dissipation test and compression test were contrasted.Combination with dissipation coefficient Cv of pore-water pressure,reasonable parameters of the stability calculation during the earth-rock dam construction were proposed.
