Abstract

The rationality of rockfall path analysis results is closely related to the resolution of the slope shape model. With the emergence of unmanned aerial vehicle (UAV) photogrammetry technology, which is suitable for engineering geological surveys, the modeling resolution for unstable rock slopes has gradually increased. In this paper, the process of constructing a model of unstable rock slopes based on UAV photogrammetry is improved. A method to obtain the geometric parameters of unstable rock masses by using the model is proposed. The movement characteristics required for rockfall analysis are summarized. Based on the analytical results of rockfalls, a method for setting up passive protective nets is suggested. A quantitative evaluation method is proposed for the protective effect of each protective scheme. Through a practical engineering case, two passive protective schemes (the original design and the optimized design based on the proposed method) are compared and evaluated by numerical simulation, and the actual site layout scheme is more similar to the optimized design scheme. The results show that the proposed method has a positive effect on the design and improvement of protective nets.
