砖混结构废墟救援安全评估 BP 模型研究
Research on Security Evaluation BP Model of Brick-concrete Structure Ruins
摘要
Abstract
The security evaluation model for structure ruins rescue can effectively serve earthquake emergency rescue work under the condition of no waste a mass of manpower and material resources.The rescue security evalu-ation model for brick-concrete structure damage seriously in earthquakes is established.Based on research status and requirement analysis of rescue security evaluation model,BP neural network model is adopted to establish the safety assessment methods and procedures,dividing points and safety level judging principle of influence factors for evaluation model are analyzed.The model is trained by using MATLAB based on the actual rescue cases and vali-dated as well as calculated by examples.The results of model validation and example calculation show that the es-tablished rescue security evaluation model for brick-concrete structure can directly applied to the safety evaluation work without exploring accurately the mechanism of structure collapse of brick-concrete structure.And the model has the following marked characteristics such as accurate results,easy operating,and convenient for engineering application.关键词
