随着经济的发展,高等级公路建设突飞猛进,且不断地向高山峡谷地区延伸,然而,高山峡谷地区存在地形地貌、地质构造、水文等不利条件,是公路建设的难点所在。因此,对山区水库淹没影响区公路建设成套技术进行研究是非常迫切和必要的。本文针对云南省山区公路建设的发展趋势和技术需求,结合该地区的具体情况,对山区公路水库淹没影响区公路总体设计技术进行深入研究,得到在高山峡谷库区公路建设过程中需确定设计思路及设计原则、科学合理的选取技术指标和保障项目安全性及可实施性的总体设计关键技术,可为相似工程提供指导性建议。
With the development of economy, high-grade highway construction by leaps and bounds, and continue to extend to the alpine gorge area, however, alpine gorge area has topography, geological structure, hydrology and other adverse conditions, is the difficulty of highway construction. Therefore, it is very urgent and necessary to study the complete set of highway construction technology in the inundation area of mountainous reservoirs. In this paper, according to the development trend and technical requirements of highway construction in mountainous areas in Yunnan Province, the overall design techniques of highway inundated area affected by road and reservoir in mountainous area are studied in detail with the specific conditions in this area. And design principles, scientific and reasonable selection of technical indicators and project security and feasibility of the overall design of key technologies that can provide guidance for similar projects.
