摘要:
排导槽是一种结构简单、效果明显、用途广泛的泥石流防治措施,在总结东川槽、"V"型槽等现有排导槽槽型优缺点的基础上,结合一种新槽型——交错齿槛型泥石流排导槽展开试验研究。提出排导槽排导指数概念,即直接反应排导槽排泄能力的参数。利用室内水槽模型试验,通过改变交错槽纵比降、齿槛间距、夹角等参数,得出排导指数与上述参数的关系,试验结果表明:1.与东川槽相比,交错齿槛槽的排导能力有大幅度的提升,最大增幅达74%,表明交错齿槛有较强的挑流排泄能力,能有效解决东川槽等存在的淤积难题;2.不同比降下,交错槽主要设计参数组合存在差异,其中10%与15%比降下,60°齿槛间距为30 cm时,交错槽的排导指数最大,...
Abstract:
Drainage channel is one the most commonly useful debris flow countermeasures with such superiorities as simple structure and convenient construction. According to the construction experience of Dongchuantype and “V-type”, an indoor flume model experiment on drainage channel with indentedsill has been performed. The definition of drainage index was proposed, i.e. a parameter of showing drainage ability of channel. In the experiment, longitudinal slope, distance between two sill and angle of sills were changed to analyze the variation law of drainage index. (1) Compared with Dongchuantype, the drainage ability of drainage canal with indentedsill increased largely with the top increment rate of 73%, that is, indented sill has obvious flow oriented effect, which is helpful to solve the problem of debrisflow siltation; (2) When the longitudinal slope is 10% or 15%, indented sill with an angle of 60 and a distance of 30cm can largely increase drainage ability of channel, whereas when longitudinal slope is 12%, the best combination is 60°and 40 cm, (3) Sills with small angle (60°) can be more fit for debrisflow with low longitudinal slope, however, sills with large angle (80°) can be more suited to debrisflow with steep gradient.
