富春江大坝船闸变形异常成因解析

Genesis Analysis of Lock Deformation Abnormity for Fuchunjiang Dam

监测资料表明,富春江左3闸墙段的上下游方向变位经常产生突变。通过定性和定量分析,对左3闸墙上下游方向变位异常进行了解析,发现主要是由于下游水位的日变化,以及每段闸墙结构状况不同和测点所处位置差异引起的,其上下游方向变位属于正常情况。

The observation data show that the displacement in the upstream and downstream direction of the left third lock chamber wall of the Fuchunjiang lock is always abnormal. The qualitative analysis and quantitative analysis for the abnormity indicate that the daily change of downstream water level, and the difference in lock chamber wall structure and observation location are the main reasons, and the displacement in the downstream direction is normal.
