喷锚支护技术自运用于重庆轨道交通暗挖隧道施工以来,系统锚杆的支护作用一直是业界争论的问题之一。通过对重庆轨道交通某地下暗挖车站初期支护的计算,将计算结果与量测资料进行对比、分析、研究,优化了重庆地区地下暗挖隧道的支护参数。
Shotcrete and anchor supporting technology has been one of the most controversial issues in the industry since it was put into operation in Chongqing Metro Tunnel construction. Through the calculation of the initial support of a underground excavation station in Chongqing rail transit, the calculation results are compared with the measured data to analyze, study and optimize the support parameters of underground tunneling in Chongqing area.
