高速铁路线路长、点多面广，沿线地理环境和地质环境均较复杂，在设计时应更注重环境选线、景观选线和地质选线。因此，深入系统地对山区高速铁路深路堑方案与隧道方案进行比较研究，具有十分重要的学术价值和工程应用价值。文章针对山区高速铁路线路中深路堑、高边坡的风险特征进行了分析，基于建成后运营安全和降低维护费用投入的角度考虑，从地质条件、结构稳定性、对环境的影响程度、视觉景观效果、施工难易程度、工程造价、运营安全等进行了综合比对，在实际工程应用中科学、合理选择设计方案，这既为工程项目安全、优质、顺利完成提供技术保障，又可为今后山岭地区高速铁路建设提供设计参考。
高速鐵路線路長、點多麵廣，沿線地理環境和地質環境均較複雜，在設計時應更註重環境選線、景觀選線和地質選線。因此，深入繫統地對山區高速鐵路深路塹方案與隧道方案進行比較研究，具有十分重要的學術價值和工程應用價值。文章針對山區高速鐵路線路中深路塹、高邊坡的風險特徵進行瞭分析，基于建成後運營安全和降低維護費用投入的角度攷慮，從地質條件、結構穩定性、對環境的影響程度、視覺景觀效果、施工難易程度、工程造價、運營安全等進行瞭綜閤比對，在實際工程應用中科學、閤理選擇設計方案，這既為工程項目安全、優質、順利完成提供技術保障，又可為今後山嶺地區高速鐵路建設提供設計參攷。

High-speed railway is featured by long route,many spots and wide areas,and complexly geographical and geo-logical environment,so route selection based on environment,landscape and geology shall be preferred in the future de-sign.Therefore,a deep and systematic study on the comparison of deep cutting and tunnel in mountainous high-speed railway has significantly academic value and engineering application value.In this paper,it is analyzed the risky charac-teristics of deep cutting and high slope in mountainous high-speed railway,and an alternative comparison is undertaken from different sides,like geological conditions,structural stability,impact on environment,visual landscape effect,com-plexity of construction,engineering cost and operational safety,given the operational safety and decrease of maintenance charge after it is completed.In practical projects,scientific and reasonable selection of design proposals provides not only the technical guarantee for the completion of projects in safety and success,but the reference for the future high-speed railway design in mountainous area.
