曲线上D型便梁与木枕撑高联合加固方法探讨

Discussion on the combined strengthening method of D-typed temporary beam and wooden blocking on the curve

针对既有线路下桥涵开挖施工中既有线半径或线间距不满足常规便梁架设要求的情况,结合有关资料进行计算,探讨了采用D型便梁与木枕撑高联合加固的可行性及实施效果,以期突破限制,提高便梁架设适用范围。

Aiming at the situation that existing railway radius or line interval of existing railway line bridge and culverts excavation construction,combined with related data calculation,the feasibility and implementing effect of combined strengthening method of D-typed temporary beam and wooden blocking were discussed,so as to break limitation and enhance temporary beam erection applied scope.
