摘要
为了解不同放置方式对无砂混凝土板过水性能的影响规律,通过水工模型试验,分析了不同密度、不同工作水头时,不同放置方式对无砂混凝土板过水流量的影响。结果表明,无砂混凝土板的密度与其透水性能呈负相关关系;无砂混凝土板水平放置、垂直入渗时比竖直放置、水平入渗时的过水流量大;工作水头越高,放置方式对无砂混凝土板的过流流量的影响越小;无砂混凝土板的孔隙率越大,放置方式对过流流量的影响越小。
In order to study the influence of different placement ways on the hydraulic performance of no-sand concrete slab,hydraulic model test was used to analyze its variation laws under different compactness and water head.Experimental research result shows that no-sand concrete slabs＇ solidity is negatively correlated with its water permeability;the vertical infiltrate with horizontal placement of no-sand concrete slab is larger than horizontal infiltration with vertical placement.When the head is higher and the porosity is lager,the impact of the placement way on water flow of the nosand concrete slab is smaller.
