通过应力观测,测定桥梁在试验荷载作用下控制截面中测定的应力值,进一步将测定值与数值模拟求得的对应值进行对比分析,结果表明:实测最大拉应力值小于数值模拟求得的最大计算值。
Through the observation of stress, the measured stress value in the control section of the bridge under test load is measured, and the measured value is compared with the corresponding value obtained by numerical simulation. The results show that the maximum measured tensile stress value is less than the maximum obtained by numerical simulation Calculated.
