基于点云数据建模的瓦亭古城西南角马面稳定性分析
Stability Analysis of the Southwestern Protruding Rampart of Wating Wall based on Point Cloud Data Modeling
摘要
Abstract
To achieve efficient and detailed modeling of complex shaped earthen sites,UAV aerial survey technology was applied to the modeling of earthen sites.Highly-precision 3D models of multiple sections of the Wating wall were constructed using Geomagic and Rhino software for point cloud data processing.The southwestern protruding rampart of the wall was selected for stability analysis under natural condition and the sensitivity analysis of Fs to the influencing factors using FLAC3D based on the strength reduction method.Based on the results of sensitivity analysis,stability prediction function of the southwestern protruding rampart was established.The results showed that:Modeling based on point cloud data can efficiently create digital models while preserving the disease features and architectural form of the physical object.Under natural condition,the safety factor of the southwestern protruding rampart was 1.473(>1.0),indicating a stable state.The development of undercutting diseases will affect its stability.The safety factor of the southwestern protruding rampart was mainly influenced by c、φ、ρ、v,where Fs decreased with the increase of ρ,and increased with the increase of c and φ.(4)A stability prediction model incorporatingc、φ、ρand v as variables could predict the stability of the southwestern protruding rampart effectively.The research results can provide a reference for monitoring the stability of the southwestern protruding rampart of Wating wall.关键词
