摘要/Abstract

摘要： 土石混合体滑坡具有分布范围广、发生频率高、规律性差等显著特点，是西部山区及其重大工程建设中最为常见的灾害类型之一，其内部复杂的土-石结构是构成该类滑坡防治困难的关键因素。为了获取土石混合体斜坡接近真实的地质结构，提出通过探窗组合法，即采用高分辨的地球物理勘探方法进行地质结构探测，并借助探坑土石结构的图像处理技术予以补充，以初步实现地质结构的精细探测及宏-细观结构模型的统一。应用该方法，对湖南省南岳区拜殿乡土石混合体斜坡进行地质结构探测，获得了该斜坡接近真实的精细地质模型。该研究方法可为揭示滑坡形成演化的结构控制机制提供基础，使滑坡的预测和防治工作更加科学合理。

Abstract: Soil-rock mixture landslides present obvious features such as wide distribution, high frequency of occurrence and poor regularity, which have become one of the most common geological disaster types in the western mountainous area and its key construction projects. The complex internal soil-rock structure is the critical factor leading to the difficulty of preventing and controlling the landslides. Hence, a new method by combining the geophysical prospecting and trenching was proposed to acquire the nearly realistic geological structure of soil-rock mixture landslides. The prospecting geological structure was conducted by high-resolution geophysical exploration techniques and supplemented using digital image processing of trench section. Thus, the precise geological structure of soil-rock mixture deposit was obtained, and the integration of macroscopic and mesoscopic geological structure was preliminarily achieved by the method. The proposed combination method was applied to investigate the precise detection of geological structure within the soil-rock mixture landslide in Baidian township of Nanyue district in Hunan province, and then the nearly realistic geological structure was obtained. This study provides a basis for revealing the structural control mechanism of the formation and evolution of landslides and makes the prediction and prevention of landslides more reasonably and scientifically.
