According to the limitation on applying the research achievement on regional rainstorm-induced road hazard into practice, formation mechanism and development patterns are analyzed and investigated deeply, then two stages on forming the rainstorm-induced road hazard are verified: ① The hydrodynamic action stage, including the rainstorm splash-wash erosion process and infiltration-seepage process; ② The hydrostatic action stage, including rainwater immersion-softening process. They are combined to establish a series interaction processes termed "splash-wash-infiltration-seepage-immersion-softening" to define the formation mechanism mode for the rainstorm-induced road hazard. full cut, full fill, cut and fill are considered to be the three typical failure patterns for the rainstorm-induced road hazard and all types are boiled down to "cumulative deformation failure → developing and catastrophe failure → hysteretic deformation failure" three failure process, in order to reflecting the occurring and evolving law for the rainstorm-induced road hazard, comprehensive and systematic analysis are implemented into every single failure mode and process. The study achievements indicate a new clue for approaching the formation mechanism and developing mode of rainstorm-induced road hazard, and are of value to disaster prevention and reduction in road engineering.
