大秦铁路是国家重点建没项目,是我国第一条开行重载单元列车的晋煤外运重要专用铁路,全长约630公里。其巾一期工程(韩茶段,茶石段,大同枢纽,秦皇岛三期煤码头)长410公里,计有土工建筑3717万立方米。铁路路基是轨道的基础,它的稳固与否,直接关系到铁路运输效率和安全。重载铁路路基由于运量大,密度大,在重复荷载作用下,要求路基不仅要具有足够的强度,而且要满足
Daqin Railway is a national key construction project, which is the first dedicated railroad to open overloaded coal-fired units in Jincheng, a total length of 630 km. Its towel a project (Hancha section, Chashi section, Datong hub, Qinhuangdao Phase III coal terminal) 410 km long, there are 37.17 million cubic meters of geotechnical construction. Railway embankment is the basis of track, its stability or not, is directly related to the efficiency and safety of railway transport. Heavy load railway subgrade due to large volume, high density, under the action of repeated load, require subgrade not only to have sufficient strength, but also to meet
