摘　　要：受自然条件限制,要跨越北塬片区修建道路,需克服高差大、地质灾害风险点多、填挖大、自然场地破坏严重等一系列问题,采用常规的市政道路、平直规划的设计理念无法达到建设预期。如何跨越高差、实现两地跨越,同时又能满足资金、安全的工程要求成为必须克服的难关。鉴于此,通过选线与场地利用的结合、场地的综合利用、边坡治理与自然地层的结合设计理念,将道路线形与美学相结合、边坡治理与防灾减灾的结合、复杂地质条件下,卵石层夹层边坡的特殊处理、高边坡与景观相结合、工程建设与生态环境保护的结合的设计方案,为今后复杂地质条件下线路选择及边坡治理理念提供参考依据。Due to the limitation of natural conditions,to build roads across the northern tableland,it is necessary to overcome a series of problems,such as large elevation difference,many geological hazard risk points,large filling and excavation,and serious destruction of natural sites.It is hard to reach the construction expectation if the design concept of conventional municipal road and straightness planning is used.How to span the height difference and realize the crossing of the two places,at the same time to meet the requirements of capital and safety engineering has become a must to overcome the difficulties.In view of this,through the design concept of combining the route selection with site utilization,comprehensively utilizing the site,and combining the slope treatment with natural strata,the design scheme of combining the road alignment with aesthetics,combining the slope treatment with disaster prevention,and under the complex geological conditions,specially treating the pebble interlayer slope,combining the high slope with landscape,and combing the engineering construction with ecological environment protection is adopted,which provides reference basis for route selection and slope treatment under complex geological conditions in the future.
