二级公路改扩建工程平纵横综合设计

Plane-vertical-transect Integrated Design for the Reconstruction and Expansion Project of Second-class Roads

为进一步补充完善二级公路改扩建工程平纵横综合设计原则及方法,论文结合具体工程阐述山区二级公路平纵横设计宜结合原有工程特点灵活选用,不宜追求高指标,应遵循"利用与改扩建充分结合、建设与运营相互协调"的原则,科学论证,拟定合理的建设方案。

In order to further supplement and improve the principle and method of plane-vertical-transect integrated design for the reconstruction and expansion project of second-class roads, the present paper used a concrete project to explain that the plane-vertical-transect integrated design of the second-class roads in mountainous areas should be flexibly selected based on the characteristics of the original project, it is not good to pursue high indicators and the principle of ＂combination of utilization, reconstruction and expansion and coordination between construction and operation＂ should be followed so as to work out the most reasonable construction scheme through scientific verification.
