The test results show that: (1) For low degree of compaction and moderate permeability of soil, sudden-ly landslides will occur at toe of slope due to the seepage of groundwater.
试验结果指出:(1)压实度较小、渗透性较佳之土壤,因地下水渗透,在坡脚产生瞬间坍方。
The latter one maintains stable globally with smaller deformation because of the effective reinforcement of piles, although the toe of slope slides locally due to liquefaction of saturated subgrade.
