柱状危岩体是边坡稳定性分析中一种重要的危岩体类型,其失稳破坏常引起高能量和破坏性的大规模岩崩灾害,具有普遍性、突发性和高频性等特点,是制约山区建设和发展的主要地质灾害之一。非连续变形分析(DDA)作为一种基于非连续介质力学的数值计算方法,具有完全的运动学理论及可靠的块体接触处理方案,非常适合模拟节理岩体系统的失稳破坏与运动过程。文章采用三维(3D)DDA方法对柱状危岩体的失稳破坏机理与破坏后的运动过程进行研究。研制了基于双目立体视觉原理的危岩体失稳破坏实验装置,开展了柱状块体系统室内实验研究,验证了3D DDA方法在分析柱状危岩体失稳运动方面的准确性。以望霞边坡柱状危岩体为例,建立边坡及危岩体3D DDA数值模型,分析柱状危岩体失稳运动全过程、动能及位移演化特征,讨论块体系统运动特性及崩塌滚石成灾机制。结果表明,柱状危岩体以滑动模式失稳,运动过程中直接与其沿途公路冲击碰撞,引发崩塌滚石地质灾害,具有高速高能等运动学特性。
Columnar dangerous rock mass is an important type of dangerous rock mass in slope stability analysis. Its instability and failure often results in large-scale
high-energy rockfall disasters with destructive power. These events are characterized by their prevalence
sudden occurrence
and high frequency
making them one of the main geological hazards that restrict the construction and development of mountainous areas. Discontinuous deformation analysis (DDA)
a numerical method based on the mechanics of discontinuous media
provides a comprehensive kinematic theory and reliable block contact handling schemes
making it highly suitable for simulating the instability
failure
and movement processes of jointed rock mass systems. This study used the three-dimensional (3D) DDA method to investigate the instability failure mechanisms and post-failure movement of columnar dangerous rock mass. An experimental setup based on binocular stereovision principles was developed to study the instability and failure of dangerous rock mass. Laboratory experiments on columnar block systems were conducted
validating the accuracy of the 3D DDA method in analyzing the instability movement of columnar dangerous rock mass. Using the columnar dangerous rock mass of Wangxia slope as an example
a 3D DDA numerical model for the slope and dangerous rock mass was established. The entire instability movement process
kinetic energy
and displacement evolution characteristics of the columnar dangerous rock mass were analyzed. The movement characteristics of the block system and mechanisms of the collapse and rockfall-induced disasters were discussed. The results showed that the columnar dangerous rock mass became unstable through sliding
and it directly collided with the highway along its path during its movement
causing rockfall geological disasters. This movement exhibited kinematic characteristics such as high speed and high energy.
