The actual loading test and finite element calculation results indicate: the maximal tension stress is within the range of permissibility and in the proximity of permissible value. 荷载实测及有限元计算结果表明:箱梁的最大拉应力在许用范围以内,但其量值在允许值附近,并且是拉应力。
To simulate actual deck pavement condition under traffic loading, double-layer scheme A and scheme B are selected as alternative scheme for comparison, combined with high temperature double-layer rutting and fatigue test. 为模拟桥面铺装层的整体工作状况,又选取两种双层桥面铺装层结构方案A、方案B,在室内进行了高温状况下复合板车辙及复合梁疲劳试验。
