摘要:
水闸底板测压管水位观测值与理论值存在一定的偏差,呈现“异常”现象。调研江苏省三河闸、嶂山闸等6座水闸,基于已有水闸渗流研究成果和实测数据,对比分析影响测压管观测数据准确性以及水位变化的闸基土质、温度场、工程运行等因素,分析扬压力与水闸沉降变化的相关性。较壤土、砂土地基,黏性土基水闸测压管水位变化影响因素更为复杂,受上下游水头差、底板轮廓线、闸基土质、温度场、工程运行等综合因素影响。水闸底板测压管水位与沉降关系密切,测压管水位偏高引起的水闸底板上浮问题应引起注意,相关研究对分析水闸底板测压管水位变化规律具有参考作用。
Abstract:
There is a certain deviation between the measured and theoretical values of the water head in sluice floor, which presents an "abnormal" phenomenon. This paper investigated six sluices such as Sanhe sluice, Zhangshan sluice etc. in Jiangsu province. Based on the research results and measured data, factors such as, types of foundation soil, temperature field and operation condition that can affect the accuracy of the piezometer tube and values of the water head at the sluice floor were compared and analyzed. Correlation between the uplift pressure and sluice settlement was analyzed. Results showed that, compared to loam and sand foundation, the influence factors of the cohesive foundation are more complicated, which are affected by the comprehensive factors such as, water head difference between upstream and downstream, shape and size of the floor, properties of the soil, temperature field and operation condition etc. The water head at the sluice floor is closely related to the settlement, uplift displacement of the sluice floor that caused by uplift water pressure should be paid attention to. Reference in analyzing the variation of water head of piezometer tube at the sluice floor is provided.
