摘要
连拱隧道边仰坡具有开挖范围大、受到多次开挖扰动的特点。以常吉高速公路中的殿会坪隧道为例,进行了边仰坡和隧道洞内的现场测试,从地质条件、地形地貌、地下水情况、施工方法和施工质量等方面分析该连拱隧道仰坡稳定性的影响因素,提出了整治措施,在实际中获得成功应用。
Multi -arch tunnel has some specific characters such as large excavation scope and repetitious disturbances during excavation. Using Dianhuiping Tunnel on Changji highway as an example in this paper, in - situ tests at side and face upward slope and tunnel are carried through. The factors related with the stability of side and face upward slope at multi - arch tunnel are analysed from the factors which include geological condition, landform physiognomy, groundwater, construction method and construction quality. Some treatment measures are presented, which are used successfully in practice.
