A　landslide　model　test　under　the　artificial　rainfall　was　built　according　to　the　rainfll-induced　landslide　in　Fujian　mountainous　area.　The　rainfall　intensity,　the　slope　types　(mainly　on　vegetation　coverage)　and　the　grade　of　side　slope　were　the　main　factors　in　the　test.　The　rainfall　threshold　of　rainfall-induced　landslide　on　shallow　bedrock　was　obtained　from　the　test.　The　relationship　between　the　cumulative　precipitation　and　slope　angle　and　slope　surface　types　was　analyzed　from　the　orthogonal　experiment　by　multiple　regression　analysis.　Results　show　that　most　slope　failures　are　caused　by　the　infiltration　of　rainwater.　Conclusion　show　that　when　the　slope　angle　and　vegetation　cover　are　given,　critical　hazard　threshold　can　be　predicted,　and　the　corresponding　landslide　sliding　time　can　be　gained　by　combining　with　the　rainfall　intensity.　©　(2013)　Trans　Tech　Publications,　Switzerland.
