摘要
山区高速公路因其要求的线形指标较高而所处环境复杂,平纵面线形不可能与地形完全吻合,对环境破坏较大。故其路线设计应从环境保护的角度出发,将环境保护作为路线选线拉坡设计的控制因素之一,尽可能在设计前期阶段将公路建设对环境的破坏降至最小,以满足社会可持续发展的需要。
On account of higher linear indicators of the demands of mountains freeway and the complicated topography, the plane and profile lines cannot be tallied completely and do a great damage to the environment. Therefore, freeway alignment design in mountain area has to be from the point of view of environment protection as one of the control factors for route plane and profile design, to reduce the damages to environment lowest during the earlier period of the design, and to satisfy the demand of social maintaining development.
