Research conclusions: The EMU test with the speed of 35 1 km／h on the experimental line shows the all properties of the slab track satisfy the design requirements and the key technologies for laying the CRTS I Slab Track is successful．The triangular compass and portal frame are used for fine adjusting the slab with fast speed and high accuracy．After adjustment，the elevation error of the top surface of the slab is less than 1 mm，the error between the central line of the slab and the central line of convex retailing stand is less than 1 mm，the gap error between the slab and retailing stand is less than 5 mm. and the high—low regularity and directional regularity between the slabs are less than 2 mm，so the technology can be widely used for laying the slab track．
