摘要
铁路在国民经济和社会发展中扮演着重要角色,文章针对某高速铁路路基沉降问题展开调查研究,并分析了路基沉降原因,然后采用动态监测与静态监测相结合的方法评价整治效果。研究结果表明,选用硫铝酸盐水泥单液浆作为注浆材料,在高速铁路路基沉降治理中具有快速、便捷且显著的效果。监测结果显示,在注浆加固过程中,路基的变形较小;同时,通过与轨道测量仪对比,发现两种测量结果的差异不超过0.5 mm。
Railway plays an important role in the national economy and social development.In this paper,the subgrade settlement of a high-speed railway is investigated,and the causes of subgrade settlement are analyzed.Then,the method of combining dynamic monitoring and static monitoring is used to evaluate the treatment effect.The results show that the use of sulphate aluminate cement single liquid slurry as grouting material has a rapid,convenient and significant effect in the treatment of high-speed railway subgrade settlement.The monitoring results show that during the grouting reinforcement process,the deformation of the subgrade is small;at the same time,by comparing with the track measuring instrument,it is found that the difference between the two measurement results does not exceed 0.5 mm.
