1.前言 近十几年,我国高等级公路的建设获得跨越式发展,高速公路通车里程已近20000公里,对国民经济和社会发展起到巨大推进作用。同时也对自然环境和社会环境造成一些负面影响,暴露出设计、施工上存在的一些问题。 保护环境是我国的一项基本国策。为消除和减轻由于公路建设对环境造成的负面影响,必须在设计阶段重视环境保护工作,通过优化设计,在设计阶段尽量避免破坏环境。2.环境保护措施
1. Foreword In recent ten years, the construction of high-grade highways in our country has made leaps and bounds. The mileage of expressways opened to traffic has reached nearly 20,000 kilometers and played a significant role in promoting the national economy and social development.

By optimizing the design, the environment should be avoided as much as possible during the design phase. 2. Environmental protection measures
