Study on the statistics -- Infiltration coupling forecast model for rainfall-induced landslide in Chongqing area

摘要

Considering the maximum infiltration depth in the role of heavy rainfall and taking into account the water pressure in tension cracks located in trailing edge of landslide, this paper revises the transfer coefficient method traditionally used to determine landslide stability factor and thrust force. What's more, based on integrating the effective cumulated rainfall and the daily maximum hourly rainfall, this article establishes the statistics-infiltration coupling forecast model for rainfall-induced landslide in Chongqing territory.
