剧冲式高速岩质滑坡运动全过程动力学机制研究是论证分析高陡斜坡岩体的破裂、变形、破坏、失稳与滑体的高速运行、碰撞解体及冲击成坝全过程的动力学规律。本文提出了工程地质条件→斜坡岩体力学性质→斜坡变形破坏机制→滑坡几何学、运动学、动力学模型→斜坡变形破坏及运动过程数值模拟仿真→高速岩质滑坡运动全过程动力学理论方程及公式→滑坡体(坝)超稳性综合分析与评价的研究途径和技术路线来解决这一问题。以川西青衣江上游宝兴河蜂桶寨水电站龙店子坝址区大板桥滑坡(坝)为例,在广泛、深入的现场调查和室内外岩土物理力学性质综合测试的基础上,对斜坡变形破坏及滑坡运动全过程的动力学机制进行了全面地、系统地研究。首先,研究了高陡斜坡所在的区域地质构造、区域构造应力场、现代地壳稳定性、区域地形地貌、水文地质及地质灾害群体发育特征等工程地质条件。其次,研究了斜坡岩体结构、斜坡岩体力学特性、斜坡变形破坏形式及机制,建立了斜坡变形破坏的地质力学模型。在深入研究滑坡发育形态、空间分区、结构特征;滑带土宏观结构、SEM微观形貌综合特征、物质成分;滑坡土石体物理力学性质、本构模型及参数的基础上,建立了滑坡几何学、运动学、动力学模型。通过有限元反演分析,基于?
The research on the dynamics mechanism of the dynamic process of the rock-slide high-speed rocky landslide is to demonstrate the dynamics of the whole process of high-speed operation, collision and disintegration of the high-steep-slope rock mass, such as rupture, deformation, failure, and instability. . This paper proposes engineering geological conditions→slope rock mechanical properties→slope deformation and failure mechanism→landslide geometry, kinematics, dynamics model→slope deformation and failure and motion process numerical simulation and simulation→dynamic theory equation of high-speed rocky landslide movement And the formula → research methods and technical routes for the comprehensive analysis and evaluation of the landslide body (dam) super stability to solve this problem. Taking the Dabanqiao landslide (dam) at the Longdianzi dam site of the Fengtongzhai Hydropower Station in the upper reaches of the Qingyi River in western Sichuan as an example, based on extensive and in-depth on-site investigations and comprehensive testing of indoor and outdoor geotechnical and mechanical properties, the slopes The dynamic mechanism of the whole process of deformation failure and landslide movement was studied comprehensively and systematically. First, the engineering geological conditions such as regional geological structure, regional tectonic stress field, modern crustal stability, regional topography, hydrogeology and geological disaster group development characteristics are studied. Secondly, the rock mass structure of the slope, the mechanical properties of the slope rock mass, the form and mechanism of the slope deformation and failure are studied, and the geomechanical model of the slope deformation and failure is established. In-depth study of the landslide development morphology, spatial zoning, structural characteristics; slide zone soil macrostructure, SEM micro-morphological characteristics, material composition; physical and mechanical properties of landslides, constitutive models and parameters, based on the establishment of the landslide geometry , kinematics, dynamics model.
