平原微丘区高速公路低路堤设计研究

Research on Design of Freeway Low Embankment in Plain Lightly Undulate Area

高填土路堤具有一系列的缺点,所以高速公路进行低路堤设计是一种必然的趋势。本文分析了造成我国高速公路路堤偏高的原因,进而给出我国平原微丘区低路堤的定义,接着分析决定路堤高度的因素,最后论述了平原微丘区高速公路低路堤设计方法要点。

The high earth filled embankment possesses a series of demerits, so the freeway low embankment design is an inexorable trend. The paper analyzes reasons forming the high embankment, defines the low embankment in highway undulate area, enalyzes factors determing embankment height, at last discusses essentials for freeway low embankment design in plain lightly undulate area.
