| 摘 要： | 本文以九瑞高速公路南阳一隧道为实例,通过介绍延长套拱和管棚处理破碎围岩半裸露型隧道洞口的加固措施,并结合"应力平衡"原理使用支撑梁抵抗围岩侧压力,以削弱开挖爆破对隧道半裸露洞口产生的震动偏压力,使隧道施工安全进洞。

| Abstract: | Taking the Nanyang 1 tunnel for example,reinforcement measures for tunnel entrance including extending the sets of arches and pipe-shed-type to deal with broken rock semi-exposed were introduced.The support beam was used to resist lateral pressure of surrounding rock based on conjunction with "stress balance" principle.These measures above can weaken vibration bias force produced during the tunnel excavation and can make sure construction security. |

| Keywords: | shattered rock half-naked non-brushing inverted slope reinforcement technique |
