- Abstract
Taking the Lixian-Guangyuan segment of Lanzhou-Chengdu-Chongqing product oil pipeline as an example, the satellite images in the study area were produced based on multi-source remote sensing information. The authors then established the remote sensing interpretation signs for debris flows according to the data of geological and ecological environment. After that, the 3D remote sensing image models of debris flows were constructed by texture mapping technique and DEM (Digital Elevation Model). Based on the satellite images and the 3D models, debris flows along the pipelines were identified, and their features were extracted for risk assessment, which were designed into the different evaluation indexes. The authors thus introduced fuzzy comprehensive evaluation model to assess the debris flows based on these evaluation indexes. According to field investigation, the identified and evaluated results were checked to be well. It is obvious that this assessment method can quickly identify debris flows along linear construction civil engineering and evaluate their risk, which would provides scientific basis for engineering disaster prevention.
