摘　　要：为了彻底整治乌鞘岭隧道整体道床病害,借助雷达监测、钻孔取芯等辅助措施对病害产生的原因进行分析,并借鉴国内部分隧道采用压注聚氨酯材料抬升整体道床的成功经验对病害进行整治,取得成功。实践证明,聚氨酯注浆抬升整体道床是处理隧道道床沉降的一种简洁高效方法。In order to thoroughly renovate the damages of monolithic tracks in Wushaoling Tunnel,the causes of track damages are analyzedby means of radar detection and core drilling,and corresponding grouting treatments with polyurethane material are successfully implemented based on the well established methods for other domestic tunnels.Practices prove that the treatment with polyurethane grouting is a simple and effective way to treat tunnel track settlement.
