The invention discloses a typhoon rainstorm type shallow landslide safety coefficient calculation method. The typhoon rainstorm type shallow landslide safety coefficient calculation method includes A, acquiring calculation parameters of landslide by means of exploration report data collection or investigation and tests; B, acquiring typhoon wind scale, rainfall intensity and duration parameters according to weather forecast; C, determining average distances between trees and calculating cracking depths of slopes; D, calculating infiltration magnification coefficients of the slopes; E, calculating safety coefficients of the typhoon rainstorm type shallow landslide. The typhoon rainstorm type shallow landslide safety coefficient calculation method has the advantages that influence of typhoon wind load is taken into consideration when the safety coefficients of the typhoon rainstorm type shallow landslide are calculated, so that the typhoon rainstorm type landslide can be realistically evaluated, and the typhoon rainstorm type shallow landslide safety coefficient calculation method is quite practical.
