| Abstract: | By analyzing the shortcomings of the cast-in-place monolithic roadbed track in metro and combining with the practical experience of China s high speed railway slab-type track,the scheme of new slab-type track structure suitable for metro operating conditions was proposed,which can unify the vibration-damping section track and the general section track and is convenient for construction and maintenance.Based on the design research of components such as track slab,self-compacting concrete layer and damping pad,the field test section was laid and the dynamic test evaluation was carried out to verify the feasibility of the proposed slab-type track.The test results provide good technical support for the engineering application of new slab-type track. |
