洪水冲击下桥梁抗毁性受力分析实验研究
Force Analysis Experiment of Bridge Invulnerability under Flood Impact
摘要
Abstract
The present study for flood impact of bridge survivability stress analysis,through the stability of the overall structure of the bridge's stress analysis,without taking into account the various parts of the bridge impact force on the bridge damage,can not improve the performance of the bridge is given to flood rationalization proposals.Put forward a new analysis method for bridge under flood invulnerability,by considering the floods over the deck and deck in either of the following circumstances,the force analysis of the bridge in the horizontal direction and the vertical direction of the key parts of the calculated torque and the corresponding displacement,further for normal and shear stresses and,by the maximum normal stress and shear stress of the comparative analysis on the flood impact under the bridge survivability stress analysis,and the establishment of flood impact analysis to verify the effectiveness of the method of experimental model of bridge survivability by.The experimental results show that the various parts of the bridge force situation is different,have different degree of influence on the survivability of the whole bridge,and is given to improve the survivability of bridge,proved that the method is effective to flood bridge survivability stress analysis results.关键词
