| 摘 要： | 古迹保护已成为目前工程界十分关注的问题。文章以徽杭高速公路昱岭关隧道为工程背景,先通过数值模拟对古城墙处隧道的拱顶围岩加固影响和施工方案优化进行分析,主要模拟了不同施工顺序对中隔墙受力的影响以及拱顶围岩加固对控制地表不均匀沉降的作用;然后探讨了古城墙下隧道爆破方案的设计。通过现场的隧道监控量测数据表明,优化的隧道开挖方案和爆破设计有效的控制了古城墙处地表下沉,保证了古城墙的完整性。 |

| Abstract: | Rampart protection has become a concerned problem.Based on Yulingguan Tunnel on Hui-Hang Freeway,influence of surrounding rock reinforcement and Construction plan optimization are analyzed by numerical simulation,which contains the middle wall stressing influence by difference construction orders and effect of controlling the differential subsidence of ground surface by means of wall rock reinforcement.Besides,design of blasting program of tunnel under rampart is discussed.From the data measured in spot,the subsidence of ground under rampart is controlled effectively by the tunnel optimization construction plan and blasting program.The double multi-arch tunnel passes through the rampart successfully. |
| Keywords: | tunnel rampart protection blasting design ground surface settlement control middle guide tunnel Yulingguan tunnel on Hui(Huizhou)-Hang(Hangzhou)Freeway |
