摘要
以辽河干流实际水文资料为依据,在沈阳农业大学水利综合实验基地实验池,通过模拟不同浪高条件,研究不同固定方式生态浮岛的稳定性差异,确定适合于辽河生态浮岛建设的合适类型。结果表明,各位移指标经方差分析和多重比较及均值比较分析,立桩式浮岛稳定性最优,索道式浮岛次之,沉坠式浮岛稳定性较差;绳索张力和沉坠位移指标经比较分析,索道式浮岛较立桩式浮岛稳定,沉坠式浮岛稳定性较差。综合考虑各项分析结果,本研究选择索道式和立桩式作为辽河生态浮岛野外段建设预实验的固定方式,经河流实际水文及其他条件检验后,选择一种最优的固定方式,指导大规模建设。
In order to select the appropriate fixed type of ecological floating island which will be applied on Liao River later,simulation test was carried out at Shenyang Agricultural University experimental pools by designing different wave height impacting the island.Based on the island＇s stabilization,alternative offer can be summed up to construct real floating island in river.Results show that judging from displacement indexs,the stability of staking-floating island is best,cableway-floating island second,and sinker-floating island worst.This conclusion was drown by method of variance analysis,multiple comparison and average values comparison.While selecting other evaluation indicators such as rope tension and sinker displacement,cableway-floating island showed best characteristics of stability,and sinker-floating island seemed much weaker.By synthesizing all of the analysis results,staking and cableway pattern were recommended in this research.This two pattern test section would be put into operation on Liao River in subsequent research plans,through which the best pattern be selected,guiding large-scale construction.
