(3) 路基边坡
路基边坡可用边坡高度H与边坡宽度b之比值来表示。
①路堤边坡
《城市道路路基设计规范》规定的路堤边坡如下：
填方路基边坡：填方高度H＜8米，边坡采用1：1.5；填方高度8＜H≤16米时，边坡坡度1：1.75。
本设计路段路堤最大高度为7.137m，故边坡取1:1.5。
②路堑边坡
挖方边坡路基边坡的设计应减少对天然植被与山体的破坏，防止诱发地质灾害。其边坡形式与坡率应根据工程地质和水文地质条件、边坡高度、排水措施以及施工方法等综合确定。
挖方路基边坡：挖方高度H≤8米时，边坡坡度1：1;8＜H≤16米时，边坡坡度1：1.5；中间设置1米宽的碎落台。
③半填半挖路基
半填半挖路基兼有路堤与路堑的特点，故应满足上述路基路堑对边坡的要求。另外，在挖方一侧宽度不足一幅行车道宽时，应该将路床深度内的原有土质全部挖除换填。

(3) the roadbed side slopeSubgrade slope can slope height h and width b the ratio of the slope.① embankment slopeCode for design of urban road subgrade under embankment slope is as follows: Earth roadbed side slope: fill height of H<8 m, slope 1:1.5; fill height when 8<H ≤ 16 m, slope 1:1.75. The design section of embankment maximum height is 7.137m, so the slope is 1:1.5.② slopeSlope of subgrade slope should be designed to reduce the natural vegetation and destruction of the Hill to prevent geological disasters. Its slope and the slope was the engineering geology and hydrogeology condition, height, slope and drainage measures and construction methods determined.Excavated roadbed side slope: cutting height h ≤ 8 meters, the slope when 1:1;8<H ≤ 16 m, slope 1:1.5; set 1 meter wide broken down in the middle.③ dig-fill subgradeDig-fill subgrade and embankment and cutting features, it should meet the requirements of cutting slope of subgrade. In addition, the cut side width less than one lane wide, road-all the original soil in depth should be removed for filling.

(3) embankment slope
embankment slope and slope height H ratio of the width b of the slope can be used to represent.
① embankment slope
embankment slope "Urban Roadbed design specifications" provides as follows:
Fill embankment slope: fill height H <8 meters, the slope of 1: 1.5; fill height of 8 <H≤16 meters, slope gradient of 1: 1.75.
The design of the road embankment maximum height of 7.137m, so take the slope of 1: 1.5.
② Cut Slope
design cut slope embankment slope should reduce the destruction of natural vegetation and mountains, to prevent induced geological disasters. Its slope form and slope rate should be determined in accordance with the comprehensive engineering geological and hydrogeological conditions, slope height, drainage measures and construction methods.
Embankment slope excavation: excavation H≤8 meters height, slope gradient 1: 1; 8 <H≤16 meters, slope gradient 1: 1.5; the middle setting 1 meter wide chipping station.
③ Cut - Fill subgrade
half - fill embankment roadbed and cutting both features, we shall meet on the slope above the roadbed cutting requirements. Further, when the cut side of the lane width is less than a width, should the original road bed soil depth within the entire excavation of replacement.

(3) roadbed side slopeRoadbed slope can be expressed by the ratio of B to slope width H.Embankment slopeThe "urban road subgrade design code" provisions of the embankment slope as follows:Embankment slope: fill height H is less than 8 meters, the slope by 1:1.5; H > 8 filling height 16 meters, slope 1:1.75.The maximum height of road embankment in this design is 7.137m, so the slope is 1:1.5.The cutting slopeThe design of excavation slope of subgrade slope should be reduced to natural vegetation and mountain damage, prevent geological disasters. The slope form and slope rate shall be determined according to the engineering geology and hydro geological conditions, the slope height, drainage measures and construction methods.The excavation of roadbed slope excavation height: H less than 8 meters, the slope gradient of 1:1; 8 H > 16 meters, slope gradient of 1:1.5; set up in the middle of 1 meters wide broken down.Half filled and half excavated roadbedHalf filling and half dug embankment with embankment and cutting, therefore should meet the requirements of cutting slope of subgrade. In addition, in the excavation side less than the width of a lane width, should be within the depth of the original soil roadbed excavation replacement.
