中文摘要:介绍了内宜高速公路K43+200~256段边坡的治理方案、施工措施。该边坡的4个危岩体除了都采取预应力锚索外,还针对不同危岩体的特征采取了不同的治理措施:W1预应力锚索+裂隙封填;W2预应力锚索+岩腔封砌;W3预应力锚索;W4预应力锚索+危岩体支撑。经过两年多时间的考验,证明该治理方案和措施是合理的。 |

Slope Treatment Measures for Nei-Yi Expressway (K43 +200~K43 +256) |

Abstract:The paper introduced slope treatment scheme and construction measures for Nei-Yi expressway (K43+200~K43+256). Besides pre-stressed anchoring cable, different treatment measures for each unstable rock mass were also applied: crack filling, rock cavity sealing and unstable rock support. It has been proved that the treatment scheme and construction measures are reasonable by time tested for more than 2 years. |
