摘要
南昆铁路路基地段长,工程难度大,在铁路建设中,路基边坡工程是主要的技术关键之一。对此,开展了碎 裂膨胀岩路基边坡处理、破碎软岩路堑高边坡挡护和路堤高边坡新型支挡结构(锚拉式桩板墙,新型拉筋加筋土挡土墙)等项结合工程的科研试验,取得突出成果,为南昆铁路的顺利建成和安全运营提供了科学依据。
The subgrade in Nanning-Kunming railway is very long and engineering conditions are complicated there. One of the key techniques is subgrade slope engineering in construction of the railway. Therefore,test and research on subgrade treatment of cataclastic expansive rock,retaining and protection of high cut slope in crushing and weak rock,and new retaining structure types of high embankment slope,such as piles-plate wall of prestressed anchor wire,reinforced earth retaining wall of new type straps,are conducted in combination with construction of the railway. Outstanding achievements of above research provide scientific foundation for smooth construction and safe transport of the railway.
