| 摘 要： | 对高桩码头纵梁的裂缝进行了调查和检测,对码头在外荷载和温度、收缩、不均匀沉降变形作用下的结构受力进行了分析,判断形成此类裂缝的主要原因是温度变形作用。提出采用纵向整体预应力和新建码头纵梁中部适当增加纵向钢筋等措施,来减轻温度变形作用的危害。

| Abstract: | Based on the investigation and detection of the cracks in longitudinal beams of piled wharf, and through analysis of the forces of wharf structures due to external loads, temperature, shrinkage and non -uniform settlement, it is concluded that the main causes of the cracks is temperature deformation. The methods of adopting longitudinal integral pre -stresses and increasing longitudinal reinforcing steel for longitudinal beams of newly constructed wharves are presented to reduce the damages due to temperature deformation. |
