This thesis gives the introduction of the construction technique of a Slab Non-ballast Track, which has been used in the Shuanghe Bridge of Qin-shen Passenger Railway, and sheds light on a series of key construction techniques, mainly including: fabrication of the trackslab, research and production of CA sand mortar, construction of concrete bearing and convex retaining wall, paving of track slab, pouring of CA mortar mixture, construction of the filled cushion slab etc. All these will have the significant reference and application value for its employment to the construction of the city overhead to rack and the express railway.
