| Abstract: | Research purposes:In recent years,continuous beam has already been the common bridge type in newly-buih railway and PDL.It is trend to lay jointless rail for newly-built railway.It is imperative to study the rules of longitudinal force of CWR on bridge and discuss the limit stiffness of pier of the continuous beams that usually used in PDL. Research results:This paper puts forward the limit stiffness of pier of continuous beams that usually used in PDL which can guide the prophase design of bridge and track. |
