在粘土路堤上出现浅表面滑移之前，安装了张力计系统来连续监测孔隙水状况。结果表明，在连续低强度降水期后，粘土路堤中会出现高孔隙水压力。通过稳定性分析证明，对于首次滑坡，粘土填充材料的剪切强度高于残余值，并且内聚力虽小但有限。
Prior to the occurrence of a shallow surface slip on a clay embankment a tensiometer system was installed to continuously monitor pore water conditions. It is shown that high pore water pressures can develop in clay embankments after periods of continuous low intensity precipitation. Using stability analyses it is demonstrated that for this first time slide, the clay fill material had a shear strength above residual values and a small but finite cohesion.
