土坡稳定性分析中的孔隙水压力问题

The Pore Water Pressure in Analyzing Landslide Stability

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。

Aiming at the current study on landslide stability, it is believed that to confirm the of pore water pressure is essential for landslide stability Combining existing problems and the Skempton formula and Jurgenson theory,an approximate computing formula is put forward for estimating pore water pressure in glutinous landslide during construction and seepage For a non steady seepage,it is desirable to determine pore water pressure in situ Finally,a relationship between landslide safety factor and pore water pressure is presented
