Dynam ic StressM easurement and Analysis of Subgrade-Culvert Transition Section on Q inhuangdao-Shenyang Passenger SpecialLine

  • Publish Date: 25 Apr 2005
  • Dynamic soil stress of a subgrade-culvert transition section from DK49+689. 0 toDK49+ 700. 7 on theQinhuangdao-Shenyang passenger special linewasmeasured and its influencing factors, including train speed, structural changes and soil depth, were analyzed. The results indicate that dynamic earth pressure trends to rise with the increase of train speed. When train speed exceeds 220 km/h, dynamic earth pressure trends to be unchanged, but it is always bigger than the earth pressure ofquasi-static state. In addition, dynamic earth pressure attenuates rapidlywith the increase of soil depth, approaching to the quasi-static earth pressure. Furthermore, it is also related to the structure of subgrade andmuch greater over the culvert than in normal subgrade.
