摘要:
水动力因素是导致泥石流发生的基本条件,目前在泥石流消除水动力的分流工程中,全部采用重力流形式,容易被泥石流所携带的泥沙淤积堵塞,导致分流结构失效。采用水石分离的虹吸排水技术,其可以利用虹吸效应,免泥沙淤积,并大幅提高排水分流效率,但目前水石分流虹吸管布置设计中缺乏管径与布置形式选择的相关研究。通过水力学分析以及公式的推导,得出了不同长度虹吸排水能力的计算公式,采用PE80管标准规格,进行虹吸管排水能力的计算,得出了可用于不同管径下虹吸管排水能力设计的基础值,针对于实际工程的复杂边坡形态提出了虹吸管排水能力的计算公式,适用于实际坡体的泥石流防治虹吸管设计。
Abstract:
Hydrodynamic factor is an important condition causes debris flow. At present, for debris flow control means all using gravity flow drainage form, such kind of form often makes the cut drainage structures failure due to siltation. Water-sediment separation by water siphon drainage technology uses siphon phenomenon to drainage, avoiding the power, in the form of full pipe flow of water across space transmission. However, in present, doesn't have a clear research on siphon drainage pipe's arrangement design for the selection of size and number. With hydraulics analysis and formulas derivation, summarized a formula for siphon drainage ability with given length, Calculated with PE80 grade polyethylene pipes, gives reference standard value siphon drainage capacity of different diameters. Moreover, summarized a formula suit for complex slope mode for designing of actual slope debris flow prevention.
