高桩码头应变监测与结果分析

Strain monitoring and results analysis of high-piled wharf

为了解高桩码头理论计算与实际情况之间的吻合状况,在主要构件上安装应变监测系统,测得码头构件在船舶靠泊、码头面堆载、岸桥作业3种工况下的应变值。分析监测结果,并与理论计算值进行对比。结果表明:(1)现场监测结果与理论建模计算的结果存在差异,但是二者的趋势是一致的;(2)加固改造方案有效;(3)对码头构件的实际受力状况有了直观了解。

In order to understand the coincidence between the theoretical calculation and the actual situation of the high-piled wharf,the strain monitoring system is installed on the main components to measure the strain values of the wharf components under three working conditions:ship berthing,stacking on wharf surface,and quay crane operation.The monitoring results are analyzed and compared with the theoretical calculation values.The results show that:(1)There are differences between the field monitoring results and the theoretical modeling results,but their trend is consistent.(2)The reinforcement scheme is effective.(3)We have a direct understanding of the actual stress condition of wharf components.
