摘要

Rainfall infiltration depth in an integrated and homogeneous soil mass is extremely limited. How does rainfall infiltrate into a loess slope developed with various fractures and holes? How do infiltration mechanisms impact slope stability? These are issues this paper researched and discussed. Using the in situ monitoring and field investigation method, it obtained that the infiltration depth of rainfall in integrated loess mass is generally limited to 3.0 m underground and there are often developed various fractures and holes in loess slopes, which usually form the rapid infiltration channels to make the rainwater seep quickly and vastly and to influence the loess slope stability greatly. It put forward that the rainfall infiltration inducing loess landslide can be divided into three modes: (1) superficial infiltration inducing landslide, (2) blockage infiltration inducing landslide, and (3) breakthrough infiltration inducing landslide. The first mode requires a long-time continuous rainfall; the second mode requires a sufficient antecedent accumulative rainfall, meanwhile a certain infiltration time; and the third mode requires certain rainfall intensity.
