研究目的: 由于铁路客运专线行车速度快、技术标准高,要求边坡防护及排水设施具有足够的强度、稳定性和耐久性。水对土体的浸泡、饱和及冲刷作用,是使路基病害产生和发展,甚至影响路基安全稳定的重要原因。选取适当的工程措施及时排除边坡及其汇集到坡脚的地表水和地下水,对保证客运专线行车安全和速度要求尤为重要。
研究结论: 综合考虑地形、地质和水文条件等因素,通过对路基边坡防护和路基防排水系统设计的研究,总结得出路基防排水工程可以采取的技术措施和处理建议,保证路基结构强度与整体稳定。
Research purposes: As the train runs at high speed on passenger dedicated railway,the technical standard of passenger dedicated line is high,requiring that the slope preservation and drainage facilities have enough strength,stability and durability. The effects of water immersing,saturating and flushing soil are the major causes for the appearance and development of subgrade diseases,and even the factors of impacting roadbed security and stability.Selecting proper engineering measures and promptly draining the water collected in slope and slope toe and draining underground water are crucial to guaranteeing the traffic safety of passenger dedicated line with high speed.
Research conclusions: Considering the conditions of topography,geology,hydrogeology and other factors,the technical measures and suggestions are offered to subgrade waterproof and drainage engineering to ensure the structural strength and stability of the subgrade through doing the study on slope protection and waterproofing and drainage system for the subgrade of passenger dedicated line.
