论述了公路选线在遇到岩溶区时的主要原则和路基设计方法,并介绍了岩溶发育的条件及影响因素。在岩溶地区修建公路时,首先应全面了解公路路线所通过地带岩溶的发育程度和查清岩溶形态的空间分布规律,以便在选线时避让或防治影响路基稳定的岩溶病害。
The main principle of highway alignment in the encounter of karst area and the design method of subgrade are discussed. The conditions and influencing factors of karst development are also introduced. When building a highway in a karst area, first of all, we should fully understand the development of karst in the route through which the highway passes and find out the spatial distribution of karst morphology in order to avoid or prevent the karst diseases that affect the stability of the roadbed during route selection.
