摘要: 本文系国家自然科学基金资助项目《桥梁抗御洪灾异相耦合破坏作用的安全性预测与仿真》研究纲要的缩影,笔者对灾害伴生过程中各物相(固态、液态、气态)之间耦合作用形态及对桥梁破坏性认识,以及对耦合作用物理模型、仿真模型的初步探讨,以期为该项目研究的展开和向纵深推进提供借鉴.

Abstract: This paper an outline of the National fund project,Bridges's Safety Prediction and Behavior Simulation under the Multi-phase Coupling Actions by Flood Water.The authors approach coupling action models among solid,liquid and gas states,while discussing bridge rupture features under these coupling actions.As one important problem of the project,physical and simulation model are discussed too in the paper.All the discussion in the paper can be a guide to deep research of the project.

Key words: bridge disaster, multi-phase, coupling actions, prediction, simulation system
