Research results:Residual strength of slip soil has linear regression with peak strength; plastic index can be better used to estimate residual strength.
研究结果：滑带土的峰值强度和残余强度比较接近，成线性关系；塑性指数能较好的用来估算残余强度。
Owing to the progressive failure of the soil, the strength may drop from peak value to residual value.
由于土的逐渐破损，会使其由峰值强度逐渐降低到残余强度。
With the increasing of bond strength between soil particles, the initial elastic modulus and peak strength of talus deposit go up at a certain level.
随着土颗粒间黏结强度的提高，堆积体的初始弹性模量和峰值强度都有所提高。
