摘要
为解决拟建宣盘高速与条件复杂的既有水盘高速的搭接问题,通过定性分析水盘高速构筑物分布情况、线形指标、廊带地物分布情况和地形地质等条件,先确定了接线点,再用定性、定量相结合的方式,并从工程规模及投资、对规划区的影响、施工期保通、交通顺畅程度等方面深入比选复合式枢纽互通(方案1)和十字枢纽兼落地互通(方案2)2种接线方案。结果表明:方案1在工程规模及投资、对规划区的影响、施工期保通等方面皆优于方案2,而方案2仅在交通顺畅程度方面略有优势,综合分析,方案1更合理可行。
In order to solve the problem of connecting the newly built Xuanwei-Panzhou expressway with the complex sections of existing Liupanshui-Panxian expressway,this paper first qualitatively analyzes the distribution of structures,linear indicators,distribution of corridor features,and geological conditions,and determines recommended connection points.Then,a combination of qualitative and quantitative methods is used to compare and select two connection schemes,composite hub interchange scheme(scheme 1)and cross hub and landing interchange scheme(scheme 2),from the aspects of project scale and investment,impact on the planning area,construction period guarantee,and traffic smoothness.The results show that scheme 1 is superior to scheme 2 in terms of project scale and investment,impact on the planning area,and construction period guarantee,while scheme 2 only has a slight advantage in terms of traffic smoothness.Overall,scheme 1 is more reasonable and feasible.
