摘　　要：柳梧铁路位于广西境内,线路穿越平南至梧州段山区时会产生大量的深路堑地段,为降低施工运营风险,减少对周边环境的影响,对多个地段深路堑与短隧道方案进行比选。通过选取2处典型的路隧比选段落,从结构稳定性、地质条件、施工难易程度、工程造价、环境影响程度、视觉景观效果、运营安全性等方面对深路堑方案与短隧道方案进行方案比选,得出推荐方案,并结合层次分析法(AHP)进行对比分析,分析结果与方案比选结果一致。通过研究分析,为今后类似山区铁路深路堑与短隧道方案比选提供参考。Liuwu Railway is located in Guangxi,and a large number of deep cutting sections are generated when the line passes through the mountainous area from Pingnan to Wuzhou.In order to reduce the risk of construction and operation and reduce the impact on the surrounding environment,several deep cutting and short tunnel schemes are compared.By selecting two typical road and tunnel comparison sections,from the structure stability,the geological conditions,degree of difficulty of construction,engineering cost,environmental impact,visual landscape effect,operating safety of deep cut plan and short tunnel scheme comparison,the recommended scheme,and combined with analytic hierarchy process (AHP) through the contrast analysis of The analysis results are in agreement with the comparison results.Through research and analysis,it provides a reference for the comparison and selection of deep cutting and short tunnel schemes for similar mountain railways in the future.
