| 摘 要： | 山区高速公路设计中，立交方案的选择是制约路线方案的重要因素，尤其是存在不良地质、改扩建、与铁路交叉等复杂条件下，需要综合考虑各方面影响因素，避免在后期施工过程中出现地质灾害。为了确保路线及互通方案的合理性，减少后期施工风险，通过对旬凤高速公路下河枢纽互通三个方案进行综合比选，选择出最优实施方案。

Study on Scheme Selection of Interchange Hub of Expressway in Mountainous Area under Complex Conditions |
| |
| Abstract: | In the design of expressway in mountainous area, the selection of interchange scheme is an important factor restricting the route scheme, especially in the complex conditions of unfavorable geology, reconstruction and expansion, crossing with railway, etc., it is necessary to comprehensively consider various influencing factors to avoid geological disasters in the later construction process. In order to ensure the rationality of the route and interchange scheme and reduce the construction risk in the later stage, through the comprehensive comparison and selection of three schemes for Xiahe interchange hub of Xunfeng expressway, the optimal implementing scheme is selected. |
