路基棚洞设计与施工技术的研究

The Research about Design and Construction Technology of Shed Hole Structure which is Used along the Mountain Road in Old Fox Tunnel

为保护老狐山隧道右线出口路基段的边坡和自然环境,减少开挖,采用棚洞的结构型式,避免由于大开挖引起的边坡或山体不稳定而产生的落石、滑坡滑塌等灾害发生。用midas数值计算软件对棚洞结构进行计算,得出棚洞结构的位移和应力,并和规范进行对比,结果显示棚洞结构是安全的。对高边坡工程的处治有一定的指导意义。

To protect exit roadbed slope and natural environment in the right line of the old fox mountain tunnel,to reduce excavation,it use shed hole structure to avoid the large excavation slopes or landslides instability arising from the rockfall,landslide and landslide disasters.Calculation software is used to calculate shed hole structure with Midas value,and acquire the displacement and stress of shed hole structure,and compared with the norm,results show that shed hole structure is safe.The paper have a certain guiding significance in the treatment of high slope engineering.
