依托连霍高速洛三段改扩建工程通过郑西高铁阌乡隧道上方这一工程案例,针对梁板式防护方案,在考虑围岩和衬砌劣化的基础上,采用强度折减法对高速公路改扩建工程中的最大挖方和超载运营两个状态的安全性分别进行了研究。结果表明隧道上方大体量挖方为控制性环节,梁板式防护方案能够保证阌乡隧道和改扩建工程的安全,所得结论为该近接工程的顺利施工提供了依据。在衬砌质量检测和无线监控手段的辅助下,顺利完成改扩建工程,证明了该研究成果的可靠性,可为类似近接工程的设计与施工提供技术参考。
依託連霍高速洛三段改擴建工程通過鄭西高鐵閿鄉隧道上方這一工程案例,針對樑闆式防護方案,在攷慮圍巖和襯砌劣化的基礎上,採用彊度摺減法對高速公路改擴建工程中的最大挖方和超載運營兩箇狀態的安全性分彆進行瞭研究。結果錶明隧道上方大體量挖方為控製性環節,樑闆式防護方案能夠保證閿鄉隧道和改擴建工程的安全,所得結論為該近接工程的順利施工提供瞭依據。在襯砌質量檢測和無線鑑控手段的輔助下,順利完成改擴建工程,證明瞭該研究成果的可靠性,可為類似近接工程的設計與施工提供技術參攷。
