Some Problems Deserving Notice in Reconstructed Highway Design and Construction in Plain and Tiny Hillock Area

我国西部除部分地区属平原微丘区外，大部分地区属山岭重丘区，山高谷深、地形复杂险峻。

Besides with parts of level cross country , western region of China is a mountainous zone , with high mountains and deep gorges , steep terrain .

分析了原有公路的特点和进行改造的原则，提出了对原有公路改造的勘察与设计观点，尤其对平原微丘区及山岭重丘区线位的确定提出了自己的看法。

From several aspects , the paper analyzed the characteristics of old road and the principle of reconstruction , and proposed its investigation , design and the determination of the location .

本文首先说明平原微丘区低路堤的定义，并论述了其优点，进而提出低路堤设计的原则，最后构建出低路堤的设计流程。

In this paper , the definition of low filled embankment of plain or hilly area is given and its advantages are explained . At last , the design principle and design course of low filled embankment freeway are discussed .

针对平原微丘区高速公路存在路基填筑过高的情况，对影响路基高度的主要因素作了分析，并提出了具体的路基高度降低对策，以降低路基高度，取得良好的社会效益。

According to condition of extortionate height subgrade in plain or hilly area , we analyses the main influencing factor of subgrade height and put forward specific countermeasure of fall on subgrade height , it can obviously reduce subgrade height and achieve nicer social benefit .
