摘要
依托宝汉高速公路石门隧道,采用理论分析、数值模拟、室内外现场试验等手段对隧道围岩松动圈确定方法进行研究,得出了石门隧道围岩松动圈的确定方法,并进行了现场测试和验证研究,最终根据研究得出的松动圈的数据优化石门隧道支护参数,既节约了成本,又保证了隧道施工过程安全。
Based on Shimen Tunnel engineering of Baoji-Hanzhong Expressway,determining the loosening circle method of surrounding rock of Shimen Tunnel is studied by means of theoretical analysis,numerical simulation and indoor and outdoor field tests.The method of determining the loosening circle of surrounding rock of Shimen Tunnel is obtained,and field tests and confirmation studies are carried out.Finally,the supporting parameters of Shimen Tunnel are optimized based on the data of the loosening circle obtained,which saves the cost,ensures the safety of tunnel construction.
