High-position landslide debris flow control method based on bottom boundary disturbance and application
The invention provides a high-position landslide debris flow control method based on bottom boundary disturbance and application. According to the method, path information of a mountain channel through which debris flow passes is obtained, and arrangement points of the multi-stage flow control turbulent flow dam are planned and determined on the mountain channel according to preset intervals. The turbulent flow dam is composed of a foundation body and a turbulent flow body, and the turbulent flow body is of a special multi-section type cylinder structure and can disturb debris flow through the unique shape of the turbulent flow body. When the debris flow passes through the turbulent flow dam, a fluidization layer of the debris flow is broken, bottom substances are disturbed and move upwards, internal substances collide with one another, and therefore the movement speed and destructive power of the debris flow are reduced. The method can reliably decelerate and control the debris flow, and the key is to interfere with the formation of the fluidization layer of the debris flow. When the method is used for dealing with high-speed remote debris flow disasters, the method is high in reliability, and therefore the geological disaster prevention and control effect is remarkably improved.
本发明提出了一种基于底部边界扰动的高位滑坡碎屑流控流方法及应用。该方法通过获取碎屑流经过的山体沟道路径信息，按预设间隔在山体沟道上规划并确定多级控流扰流坝的布置点。扰流坝由基础体和扰流体构成，扰流体采用特殊的多段式柱体结构，能通过其独特形状对碎屑流产生扰动。当碎屑流经过扰流坝时，其流态化层被打破，底部物质受扰动并向上运动，导致内部物质对撞，从而降低碎屑流的运动速度和破坏力。此方法能够可靠地减速和控制碎屑流，其关键在于干扰碎屑流的流态化层形成。在应对高速远程碎屑流灾害时，这种方法可靠性强，从而显著提升了地质灾害防治的效果。
