McNally支护系统在TBM掘进中的不足与改进

Deficiency and improvement of McNally supporting system for tunneling with TBM

结合工程实际,从Mc Nally支护系统理论设计支护方案出发,对Mc Nally支护系统在TBM掘进过程应用中的不足进行分析,并对各不足点提出改进措施,使其快速、安全、可靠的支护特点在施工中得到了充分发挥,同时并就该支护系统对后续施工的影响进行了具体的分析,为今后Mc Nally支护系统在国内工程上全面推广、改进应用提供参考。

Combined with engineering practice,the deficiencies of the Mc Nally supporting system during the tunneling with TBM are analyzed herein from the aspect of the supporitng system designed with the theory of Mc Nally supporting system,and then the relevant improving measures are proposed for all the deficiencies,which bring its fast,safe and reliable supporting properties into full play,while the impacts from the supporting system on the subsequent construction are specifically analyzed,so as to provide a reference for the full popularization,improvement and application of the Mc Nally supporting system to the relevant projects in China in the days to come.
