Paper Title:
Experimental Study and Evaluation on Bearing Capacity of Slab Culverts in Da-Qin Railway
  Abstract

Abstract. The experimental research on heavy haul railway existent diseases under double disadvantage fatigue load of special high stress level and multiple cycle index in da-qin railway, the bearing capacity of existing slab culverts are calculated and analyzed on ultimate limit state and serviceability limit state. According to 1:1 scale,laboratory test study on cover plate’s deflection, crack, strain of tensile steel about one piece of slab culvert in different static load and assess the cover plate’s initial state maximum carrying capacity;and for the other two pieces of cover plates, static load below 30t compression was applied until concrete cracking in order to carry on fatigue test for simulating axle load in heavy haul railway, to detect the bearing capacity of the plate and assess the service life of slab culvert. It puts forward some suggestions for the further research field in slab culvert and provides a theoretical support and practical experience for present situation and service life on existing heavy haul railway.
