| 摘 要： | 通过河床介质分布特征的分析,提出了介质筛护岸技术.通过现场试验,获得了桃花江近岸土壤的水分特征曲线,进而设计了渗流、稳定和疏干过程模拟方案,对3个连续过程中的水位变化进行了分析;计算了护岸含水层的给水度（0.14～0.21之间）,如果将7.364 km的石砌河堤改造为介质筛岸堤,设定两岸50 m宽为有效补给区时,枯水季节潜水补给量接近1 600 m^3/d,占桃花江近期补水规划的1.8%,说明介质筛岸堤具有明显的迟滞补枯作用.

| Abstract: | From analyses on the construction of riverbed,a media sieve technique for riverbank protection was proposed. Based on the spot experiments,the soil-water retention curve of the bank in Taohua River was obtained. Further,a simulation scheme including infiltration,stabilizing and drainage processes was applied to analyze the groundwater table movement. Specific yield of the unconfined aquifer close to the river is 0.14-0.21. If the original concrete bank with a length of 7. 364 km were embanked by the proposed technique above,the aquifer would supply 1 600 m^3/d of water to the river in low water season, which was about 1.8% water of the supply plan in the near future. |
