水利水电工程边坡的工程地质分类(上)

Engineering geologic classification of slopes for water resources and hydropower projects

在总结工程实践的基础上提出了适合水利水电工程 (主要是中、小型工程 )的边坡工程地质分类 ,将未变形边坡概分为岩质边坡和土质边坡 ,分别按其结构和岩性进行边坡分类 ;对变形边坡则按其变形特征进行边坡分类。对各类边坡概述了其主要特征、影响稳定的主要因素、与水利水电工程关系、处理原则与方法和勘察应注意事项等。由于全文较长 ,本刊将分上、中、下三部分连载。本期刊登的为第一部分 (上 ) ,文中概述了分类的目的和基本原则 ;简要叙述了土质边坡的分类 ,按土性划分为粘性土、砂性土、黄土、软土、胀缩土、碎石土和岩土混合共 7类土质边坡 ;并附土质边坡分类表。对土质边坡工程的勘察设计有重要参考意义。

On the basis of engineering practice,the engineering geologic classification of slopes for medium sized and small water resources and hydropower projects is put forward.The undisplaced slopes are classified into rocky and earth slopes according to their structure and lithologic characters and the displaced slopes are classified according to their displacement characteristics.The various types of slopes are outlined in respects of their main characteristics,major effecting factors on stability,relationship with hydro projects,treatment principle and methods and attentions to be paid in exploration.The paper is long and will be published in three parts.The first part describes the purpose and basic principle of classification and the classification of earth slopes into 7 types of clayey earth,sandy earth,loess,soft earth,swell shrink earth,debris earth and rock earth slopes.
