水利工程中山区公路线形设计探讨

Study on Design for Line Form of Mountain Highway in Hydraulic Project Construction

与平原区相比,山区公路选线定线具有线形复杂,受地形、地质条件的影响,以及外业勘测时需综合考虑满足路线纵坡坡度、坡长及横断面要求等特点。通过对山区公路的常见平面线形的特点分析,提出了山区公路选线设计和外业勘测时应该遵循的准则,以及注意事项,并针对一个工程实例进行分析,供设计参考。

Compared with the highway in plato region, the mountain highway has such the characteristics as being complex in its line forms, subjecting to the influence of geography and geology, considering the hne s longitudinal slope gradient, length and cross section synthetically in field survey and so on. Through the analysis on the plane line forms of the mountain highway, the criteria in the line design and field survey of the mountain highway as well as the matters needing attention are put forward to provide references for the desigh.
