摘要
西南铁路多处山区,地形、地貌、地质构造复杂,桥隧占比高,高陡边坡常位于深路堑和隧道洞口。本文通过研究行业规范、标准对高陡边坡的分类原则,结合西南山区铁路边坡工程特性,界定了西南山区高陡边坡的范围。针对西南地区的地形地貌地质情况复杂,结合西南山区铁路深路堑高边坡采取多种综合防护措施,总结了针对不同地质岩性常用的高陡边坡防护方式和索道、脚手架两种施工辅助措施,分析了高陡边坡防护工程的定额,以满足工程建设和计价需求。
The railways in the southwestern areas are located in multiple mountainous areas,with complex terrain,landforms,and geological structures.The proportion of bridges and tunnels is high,and high and steep slopes are often located in deep cuttings and tunnel entrance.Based on the study of the classification principles of high and steep slopes in industry norms and standards,combined with the engineering characteristics of railway high and steep slopes in southwest mountainous areas,this paper defines the research scope of high and steep slopes in southwest mountainous areas.In view of the complex topography,geomorphology and geological conditions in Southwest China,a variety of comprehensive protection measures have been taken in combination with the high slopes of railway deep cuttings in mountainous areas of Southwest China,and the commonly used protection methods for high and steep slopes and two auxiliary construction measures of cableways and scaffolding for different geological lithologies are summarized.The quota of high and steep slope protection engineering has been analyzed to meet the needs of engineering construction and pricing.
