冷水河特大桥结构主桥静载试验研究

Static Load Test Study of the Main Bridge of the Cold Water River Bridge

为了解在静载作用下冷水河特大桥结构受力情况,文中设计了静载试验,对静载参数与理论计算值进行了对比分析,建立冷水河特大桥模型进行数值模拟。通过模型计算与现场实测值对比,荷载试验现场实测值与模型理论计算值吻合度较高,挠度与荷载效应呈现线性关系,且冷水河特大桥主桥在静荷载作用下,可以满足设计允许荷载的正常使用要求。

In order to understand the structural stress situation of the Lengshuihe River Bridge under static load,a static load test was designed to compare and analyze the static load parameters and theoretical calculation values,By conducting numerical simulation on the Lengshuihe Bridge,a corresponding model was established,and the calculation of the model was compared with the on-site measured values.The research shows that the on-site measured values of the load test are in good agreement with the theoretical calculation values of the model,and the mechanical performance of the main bridge of the Lengshuihe River Bridge under static load can meet the normal use requirements of the design load standards.
