在建公路削坡对已建铁路边坡稳定性的影响

Stability effect on built railway slope in the construction of highways slope cutting

针对山区顺沟,顺河,沿坡并行先后修建的公路与铁路,因后筑公路工程削坡,有可能造成先筑铁路工程边坡的不稳定进行了分析,分析表明,若通过验算表明需对边坡进行加固时,一定要采取边开挖边支护的施工工艺,防止在施工期内对先建工程造成损失,并且分析时最好应考虑火车轮轴的动荷作用。

For the mountains along ditch,river and the slope, has built a parallel road and rail,after the building due to slope cutting highway projects,it may result in building the first railway project to conduct an analysis of slope instability.Analysis shows that,if the slope by checking that the need for reinforcement,they must be taken while excavating while supporting the construction process during the construction period to prevent the construction of the first losses.And the analysis is best to consider the role of a train axle dynamic load.
