(4) 路基填料标准Standards for Subgrade Fill
正线路基基床分为表层和底层，表层厚度0.6m，底层厚度1.9m。总厚度2.5m。
Main line subgrade ballast includes surface and bottom layer, with the former 0.6m thick, the latter 1.9m thick. It is 2.5 m thick in total.
基床表层应采用AB组填料。底层填料应采用B组填料，基床以下部分填料可选用A、B、C组填料。
Ballast surface shall adopt fill from Group A and B. Bottom layer shall adopt Group B fill and sections below the ballast may adopt fill from Group A ,B and C.
(5) 地基处理Foundation Treatment
1) 稳定斜坡上地基表层的处理，应符合下列要求：
Treatment of foundation surface of stable slope shall comply with the following requirements:
地面坡率缓于1:10时，路堤可直接填筑在天然地面上。路堤高度小于基床厚度的地段，应清除地表草皮。
When the ground gradient is less than 1:10, the embankment can be built on the natural ground. At sections where the height of embankment is lower than the thickness of ballast, the surface turf shall be removed.
2) 地面坡率为1:10～1:5时，应清除地表草皮。
When the ground gradient is 1:10~1:15, the surface turf shall be removed.

3) 地面坡率为1:5～1:2.5时，原地面应挖台阶，台阶宽度不应小于2m。当基岩面上的覆盖层较薄时，宜先清除覆盖层再挖台阶。当覆盖层较厚且稳定时，可予保留，在原地面挖台阶后填筑路堤。
When the ground gradient is 1:5~:1:2.5, steps with width of not less than 2m shall be built on the original ground. When the capping over the bedrock is relatively thin, it shall be removed before steps are built. When the capping is relatively thick and stable, it may be retained and the embankment can be built on the original ground after steps are built.
(6) 路基横断面Cross Section of Subgrade
1）路基面横向坡度 Cross Gradient of Subgrade Surface
本线所经过地区平均年降雨量30mm左右，站线路基有条件则设2％横向坡度，困难时可设平坡。
Considering that the average annual rainfall in regions the line passes is around 30mm, subgrade of station track shall have a 2% cross gradient if conditions permit and otherwise have a level grade.
2）路基边坡  side slope for subgrade
挖方地段仅在那林苏海特站尾部，路基边坡采用1：2。
Excavation only occurs at the end of the Nariin Sukhait station and side slope of subgrade here has a 1:2 gradient.
普通土路堤填方高度8m以内时，边坡采用1：1.5；路堤填方高度超过8m时，上部8m边坡采用1：1.5，8～15m边坡采用1：1.75。
When the fill height of common earth embankment is less than 8m, the side slope takes a 1:1.5 gradient; When the fill height of embankment is greater than 8m, the side slope takes a 1:1.5 gradient for the upper 8m and a 1:1.75 gradient for 8~15m;
3）站房区外侧土方宽度采用6.0m，扳道房及生产房屋外侧土方最小宽度采用3.0m。
The width of the earthwork outside the station buildings takes 6.0m and minimum width of the earthwork outside the switchman’s cabin and production buildings takes 3.0m..
4）路堤坡角外设置不小于2.0m宽天然护道。
The natural berm not less than 2.0m wide shall be built beyond the embankment toe.
2. 路基土石方调配原则及与区间土石方调配的协调情况
Principles of Allotment of Subgrade Earthwork and Conditions of Coordination of the allotment of subgrade earthwork and section earthwork.
（1）土石方调配原则
Principles of Earthwork Allotment
1) 路基土石方调配应采用经济、合理的调配方案。贯彻节省用地，少占良田和林地；充分利用挖方，移挖作填。当移挖作填的填料性质不符合要求时，另选择符合规定的土源作为路基填料。
Subgrade earthwork allotment shall adopt plans that are economic and reasonable. Principles of conserving land use and refraining from occupying arable land and forest land shall be implemented; excavation shall be put to full use and may be transported to other places as filler. When the excavation fail to meet demand of the filler in nature, alternative qualified soil sources can be taken as the subgrade filler.
2) 对填方地段，分别选择满足基床表层、底层、路基下部填料要求的土源，进行调配。
For fill sections, soil sources capable of respectively meeting requirements of filler for ballast surface, bottom layer and the lower part of subgrade shall be picked for allotment.
3) 各站取土场的储量、种类以地质专业提供的土源化验报告为准。
Reserve and type of various borrow grounds shall be determined by the soil source report furbished by the geological trade.
