数据分析法确定嶂山闸闸基渗透压力
摘要:闸基渗透压力是影响水闸闸室稳定的关键性因素。当水闸同时受到上下游水位差、基底承压水头、粘性土地基扬压力滞后等多重因素作用时,闸基渗透压力的估算就变得比较困难。通过对嶂山闸闸基历年实测渗透压力数据进行统计分析,初步揭示其基底渗透压力的变化规律,为该闸闸室稳定性分析提供依据。
Abstract:The seepage pressure on the base of the sluice is a very important force, which influences the stability of the sluice tremendously. When the sluice is influenced by many factors such as the water head upstream, the water head of the aquifer and the seepage lagging of clay foundation, it is very difficult to estimate the value of the seepage pressure on the sluice bottom. A series of data on Zhangshan sluice are analyzed to find the changing rules and the influential factors of the seepage pressure, which laies the base for the stability calculation.
