干热河谷地区地质特征及选线对策研究

摘要:

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综合论证分析。研究充分分析地区地质特征,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,提出干热河谷地区地质情况下,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。

Abstract:

Based on the research of route selection in the dry-hot valley area of Yuanjiang County, Yuxi City. Comprehensive demonstration and analysis of the geological characteristics of the dry and hot valley area and its influence on the expressway route plan. The study fully analyzes the geological characteristics of the region, and combines the concepts of geological route selection and disaster reduction route selection, consider the impact of engineering geological characteristics and environmental sensitive points in the route corridor. 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 basis and reference for geological research in similar areas and route selection of high-grade highways under similar geological characteristics.The results can provide basis and reference for geological research in similar areas and route selection of high-grade highways under similar geological characteristics.
