汽车荷载作用下桥梁变形模拟研究

Study of Bridge Deformation Simulating under Action of Auto Load

采用超声波无损检测技术对某实际工程现场梁体的弹性模量进行测定。通过模拟计算得到桥梁的横向挠度值,并与现场检测结果进行对比分析,得出校验系数,进而得出该荷载等级下桥梁的工作状况,达到对该桥承载力和正常使用状态进行评估的目的。

Modulus of elasticity of beam body in situ of a certain actual engineering is determined undamaged detecting techniques using the ultrasonic wave. By way of simulation calculation, the transverse deflection value of bridge has been obtained and compared with detecting results in the field , having gotten the checking coefficient, further gained the working state of bridge under present graded load and attained goal to estimate the bearing capacity and normal service state of present bridge.
