红粘土在贵州水利工程中的应用

Application of Red Clay to Irrigation Works in Guizhou

贵州水能资源居全国第六位,且具得天独厚的开发条件。在沉积岩地区、亚热带、多雨环境中,经长期的溶滤过程,可溶盐、硅被溶蚀、流失,而三价铁、铝氧化物则残留、富集,形成了牢固的团粒结构的集合体型的红粘土,在全省广为分布,取之不尽,是较好防渗建筑材料。但应用它须认识和了解它,为此归纳了红粘土的含义,总结了红粘土的特性和提出了可遵循的填筑标准,并介绍我省运行良好的、施工中又修改设计方案的、隐患病险的、失事的四种类型的水利工程实例。

The water power resources in Guizhou occupy the sixth place in China and enjoy exceptional advantages of exploiting conditions. In sedimentary rock area, subtropic area and rainy environment, solubility salt and silic are soluted and lost, but oxides of Fe+++and Al+++are left and enriched, forming fixed granular structural red clay assemblage bodies, which are widely distributed in Guizhou and are better building materials of preventing seepage. In order to realize, comprehend and utilize them, this paper concludes the implication of red ciay, sums up the featuresexamples of it and puts forward the standard of stuffing construction. In addition, the paper introduces four types of irrigation works examples of running well, but revising designing plans in construction, there being hidden trouble and danger and causing accidents, etc.
