融水县九美屯滑坡险情处理方案设计

Treatment scheme for landslide at Jiumeitun village of Rongshui County

融水县九美屯滑坡险情发生在公路上方一侧山坡处。为了避免滑坡体形成堰塞湖对上下游村屯的影响,通过综合分析及方案比选,最终确定以"疏导洪水"为理念,新建排洪隧洞,并采用新奥法施工的设计方案。该方案对滑坡体影响小,施工安全性高、灵活简便,且工期较短果。实施后达到了避开滑坡体影响及排除险情的目的,经汛期洪水考验,运行良好。

Landslide occurred on a slope by the road at Jiumeitun village of Rongshui County.In order to prevent barrier lake formation to endanger the upstream and downstream villages,based on comprehensive analysis and comparison of alternatives,it was determined to construct new discharge tunnel by new Austrian tunneling method following the concept of diversion flood.This scheme renders less influence on the sliding body,permits construction safety,flexible and convenient construction and shorter construction period.The tunnel had been constructed to eliminate danger without influence on the sliding body,and had withstood well the test of flood.
