【摘要】 因受到地形及地质等条件的限制,以及经验、技术和经济发展状况的影响,山区公路线形设计面临较大困难及挑战。结合云南山区某公路设计,对山区公路路线设计中的线形选择、前期地质、高地震烈度区选线、线形指标选用等进行分析,并对山区公路路线设计中容易忽视的问题提出建议,对于提高山区公路路线设计水平有一定的参考价值。更多还原

【Abstract】 The highway route design in mountainous area is largely restricted by the topographic and geologic condition,lacking technology and experience and economic development.Therefore,it is resulted that the route design will face great difficulty and challenge.Basing on the highway route design in Yannan mountainou area,the paper analyzes some issues in highway route design in mountainou area,such as the routine selection,prophasal geology,high seismic intensity region,route leane,etc.At the same time,some suggestions on the easily-ignored issues in highway route design in mountainous area are given pertinently.It has some reference value to improve the level of the highway route design in mountainous area.更多还原
