干热河谷地区地质特征及选线对策研究

Research on Geological Features and Route Selection Countermeasure in Dry-hot Valley Region

以玉溪市元江县干热河谷地区高速公路项目选线为研究背景,对干热河谷地区地质特征及其对高速公路路线方案的影响进行了综合论证分析。研究充分分析了地区地质特征,结合地质选线及减灾选线理念,考虑路线走廊内工程地质特点、环境敏感点等影响,通过多方案路线比选,提出了干热河谷地区地质情况下的路线选线原则和选线方法。成果可为同类地区地质研究及类似地质特征条件下高等级公路选线提供依据和参考。

Based on the research of route selection of expressway project in the dry-hot valley region of Yuanjiang County in Yuxi City,the geological features of the dry-hot valley region and its influence on the route election of expressway are comprehensively demonstrated and analyzed.The study fully analyzes the geological characteristics of the region.Combined with the concepts of geological route selection and disaster reduction route selection,the impact of engineering geological characteristics and environmental sensitive points in the route corridor is considered.Through the comparison and selection of multiple alternative routes,the principle and method of route selection under the geological conditions of dry-hot valley regions are proposed.The results can provide the basis and reference for the geological research in similar areas and the route selection of high-grade highways under the similar geological characteristics.
