潮州供水枢纽拦河闸变形分析

为监控深厚软基上拦河水闸的运行安全,潮州供水枢纽布设有上下游水位、闸坝水平位移、垂直位移、扬压力和地基反力等监测项目。根据闸坝闸墩运行期水平位移和垂直位移的监测数据,分析位移值的大小、变化趋势和分布规律。结果表明东西溪水闸闸墩均随时间逐渐向下游移动,存在上游大、下游小的不均匀沉降,变形值和变形差存在一定的趋势性增大。初步判断拦河闸工作性态基本正常,后期应加强观测,及时分析反馈指导闸坝运行。

Deformation Analysis on Sluice of Chaozhou Water Supply Project

To monitor the safety of a sluice on the deep soft foundation during operation, upstream and downstream water level, sluice horizontal displacement, vertical displacement, uplift pressure and subgrade reaction and other monitoring projects have been set in Chaozhou water supply project. Depend on the monitoring data of sluice pier horizontal and vertical displacement during operation, the displacement size, trends and distribution have been analyzed. And the results show that sluice pier is gradually moving downstream where differential settlement exists and the upstream side of the pier is greater than downstream, the difference between the value of the deformation and deformation value is in a trend of increasing. Deformation monitoring results reflect the working behavior of the sluice is in normal, it is recommended to strengthen post-observation, analysis and timely feedback to guide sluice operation.
