    水电工程倾倒变形体分类及其判识初探

    PRELIMINARY STUDY ON CLASSIFICATION AND IDENTIFICATION OF TOPPLINGS IN HYDROPOWER PROJECTS

    • 摘要: 倾倒变形体是一类十分复杂的地质体,长久以来缺乏对其进行系统的分类研究。在对西部水电工程典型倾倒变形体发育特征调查统计的基础上,按照单因素和多因素两个维度对倾倒变形体进行类型划分。以岩层倾向、发育诱因、变形部位和变形阶段为单因素分类依据,以岩性组合和岩体结构、坡体结构、变形破坏方式等为多因素分类依据,并对以包含时间场的变形时效为依据的新型分类方法进行了初探,给出了野外识别和判定倾倒变形体及其分类方法和依据。以变形破坏方式划分得到的分类为基本名称,其他划分依据下的倾倒模式为附加修饰,对倾倒变形体进行综合定名,此方法可以较为全面地反映一个倾倒变形体的综合特征信息。

       

      Abstract: As a complex geology, there is no systematic research on the toppling classification until now. Based on the development characteristics investigation of typical topplings in western hydropower projects, the topplings are classified across two dimensions:single factor and multiple factors. Rock formation tendency, genesis, deformation position and deformation stage are used as single-factor classification basis. Lithology combination and rock mass structure, slope structure, deformation failure mode are taken as multi-factor classification basis. This paper also carries out a primary research on the deformation aging classification for a toppling. The analytical approach above provides a new orientation for the toppling field identification and systematic classification. Take the classification result on the basis of deformation failure mode as the base name for a toppling to define, while others as the additional modification for comprehensive name. This new naming method can reflect the feature information of a toppling more comprehensively.
