Marly crack and deterioration of many bridge deck overlays have been attributed to the traffic load, nature factor and high thermal or shrinkagestress development in the concrete.
混凝土桥面铺装在交通荷载、自然因素、温度与收缩应力综合作用下,普遍出现了早期开裂与破坏。

The large shrinkagestress and thermal stress induced by ineffective measures for concrete curing and temperature insulation are the main causes at middle and later stages.
由于后期养护和保温措施不力产生较大的收缩应力和温度应力是引发中后期裂缝的主要原因。

The tensile stress induced by restrained thermal and autogenous shrinkage deformations was the main driving force of cracking in concrete at early age.
