To reduce building risks in landslide-prone areas and guide disaster mitigation measures，a comprehensive vulnerability analysis method was proposed based on Entropy Weight Method(EWM)-Analytic Hierarchy Process(AHP) and trapezoidal-semi-trapezoidal membership functions. Using the Sifangbei landslide in Wanzhou District，Chongqing，as a case study. The landslide failure probability was calculated using the Morgenstern-Price and Monte Carlo methods. Field surveys of building attributes were used to analyze landslide hazards and validate the analysis method. The results indicate that the composite model using crack indicators provides reliable vulnerability analysis for buildings in the Sifangbei landslide zone. The proposed method is feasible. The landslide is most dangerous when the reservoir water level drops from 175 m to 145 m. Combined with a 50-year rainfall event，leading to over 7.5 million yuan in economic losses. Vulnerable buildings are mainly located in the middle and rear parts of the landslide and along its right boundary.
