摘　　要：隧道洞口边坡的整体稳定对隧道正常运营至关重要,针对宜长高速公路江苏段隧道洞口陡峭、富水地质情况,采用高强面板格宾和加筋麦克垫联合加固坡底,并进行二级边坡绿化防护,确保了隧道洞口边坡体的整体稳定,有效避免了降雨对边坡土体的冲刷。该结构具有绿色、环保、节能的优点,对我国同类边坡工程防护具有重要的指导意义。The stability of slope at the tunnel entrance is important to the highway normal operation. According to the steep and water-rich stratum in the Yichang highway tunnel, the gabion wall together with reinforced MAC pad structure is used to reinforce the slope. The slop greening method is used to reinforce the secondary slop in the conservation of soil. This structure enhances the stability of slope in the tunnel entrance and avoids the soil erosion. The proposed reinforce method has advantages of green, environmental protection and energy conservation. It can provide guidance to other similar engineering.
