针对土坡稳定性研究现状 ,认为孔隙水压力的确定对土坡稳定性分析十分重要。从实际问题出发 ,根据 Skempton公式和 Jurgenson弹性理论 ,提出了粘性土坡施工期和渗流期的孔隙水压力近似计算公式。但对于非稳定渗流 ,建议最好采用现场原位测试其孔隙水压力。最后阐述了土坡安全系数与孔隙水压力的关系。
According to the research status of soil slope stability, it is considered that the determination of pore water pressure is very important to the stability analysis of soil slope. Based on the Skempton formula and the Jurgenson elasticity theory, the approximate formulas for calculating the pore water pressure during the construction and seepage phases are proposed. However, for unsteady seepage, it is advisable to test the pore water pressure in situ using in situ test. Finally, the relationship between safety factor of soil slope and pore water pressure is expounded.
