The objectives are exploring the impacts of geologic hazards on the construction of homestays, improving the safety of homestay buildings, guaranteeing the safety of tourists, and enhancing the disaster-resistance of homestays in scenery spots. The computer simulation system and Building Information Modeling (BIM) technology are employed to construct a geologic hazard prediction model for homestays. The model utilizes a time history method to establish a complete early-warning and monitoring system by learning the geologic disaster data. The detection of various geologic hazards has verified the effectiveness of the proposed model. The results show that the model can reduce the losses in the case of water accumulation and landslides during storms, and the BIM technology-based homestay buildings will suffer fewer losses. In the case of earthquakes, BIM technology-based homestay buildings have no noticeable shaking and displacement. Compared to traditional construction methods, the displacement is reduced by 49.15%. In the case of a spontaneous fire, the burning area of the BIM technology-based homestay building is only 270m2. The most severe factors affecting the construction of homestay buildings are earthquakes and landslide risks. The BIM technology generates 3D building planning; therefore, planners can fully understand the problems in the building. In the meantime, the multi-source monitoring data of multiple geologic hazards can be monitored and fed back, thereby improving the timeliness of early-warning of geologic hazards. The results are of considerable significance to the prevention of losses caused by geologic hazards, which can significantly improve the understanding of geologic hazards.
目的是探索地质灾害对民宿建设的影响，提高民宿建筑的安全性，保障游客安全，增强景区民宿的抗灾能力。利用计算机仿真系统和建筑信息模型（BIM）技术，构建民宿地质灾害预测模型。该模型采用时程分析法，通过学习地质灾害数据，建立完整的预警监测系统。对各种地质灾害的检测验证了所提出模型的有效性。结果表明，该模型可以减少暴雨积水和滑坡造成的损失，基于 BIM 技术的民宿建筑损失较小。在地震情况下，基于 BIM 技术的民宿建筑几乎没有晃动和位移。与传统施工方法相比，位移减少了 49.15%。在自燃火灾的情况下，基于 BIM 技术的民宿建筑的燃烧面积仅为 270m2。影响民宿建筑建设的最严重因素是地震和滑坡风险。BIM 技术生成 3D 建筑规划；因此，规划人员可以充分了解建筑物中的问题。同时，可以监测和反馈多种地质灾害的多源监测数据，从而提高地质灾害预警的及时性。研究结果对预防地质灾害造成的损失具有重要意义，可以显著提高对地质灾害的认识。
