大中型水闸底板垂直位移变化机理分析

Analysis of Vertical Displacement of Large Sluice Baseboards During the Operating Period

根据大型水闸建成运行期20年的垂直位移观测资料,从土层的弹塑性模型角度,对汛期和非汛期、上下游水位变化工况下基础土层应力状态进行分析,定性地解释了大型水闸运行期底板上浮的现象。

Based on vertical displacement of observational data of large sluices built to run under the period of 20 years, baseboards stress was analyzed in view of elastic - plastic soil model during the flood season and non - flood season and the changes of upstream and downstream water level. Qualitative interpretation was made about the phenomenon of floating floor in the operation of a large - scale sluice.
