摘要
2003年6月10日,三峡水库蓄水至135m高程后,永久船闸建筑物闸顶从一闸首至六闸首沉降量有明显差异,拟合模型计算结果说明,在水库蓄水后的垂直荷载影响下,船闸建筑物的垂直位移表现出线性均匀的变化特征。由于船闸建筑物与开挖岩体为整体结构,因此,这种垂直位移特性实质也是岩体的垂直变形的具体表现。
Since water impoundment to 135 m on June 10th, 2003 of Three Gorges Project, there were obvious differences in settlement on the top of its permanent shiplock structures from the first lock head to the sixth one. The calculation results of distribution model showed that the vertical displacement of shiplock structures should be a linear, even characteristic change under the influence of vertical load after reservoir impoundment, lnfact, this characteristic was manifestation of the vertical displacement of the rock mass.
