摘要
以合璧津高速公路九峰山段为依托,从工程实际着手,多角度论述了应对危岩落石的防范措施,并进行综合处理方案设计。采用了陡坡段隧道方案通过危岩落石集中区域,对隧道外的危岩分别采用主动和被动防治技术,其中被动防治使用了落石模拟技术确定防护构造物几何尺寸和避让距离,并优化最终路线线位,为类似地区公路工程项目的危岩防治提供一定参考。
Based on the Jiufeng Mountain section of Hebijin Expressway,the preventive measures for dealing with dangerous rockfall were discussed from various perspectives,and the comprehensive design was completed with regard to the engineering practice.The scheme of steep slope tunnel was adopted to pass through the concentrated area of dangerous rockfall,and the active and passive prevention and control techniques were adopted for the dangerous rocks outside the tunnel respectively.As for the passive prevention and control technique,the simulation technology of rockfall was used to determine the geometric size of protective structure and evaded distance and to optimize the final route,which provides reference for dangerous rock prevention and control of highway projects in similar areas.
