摘要:
为及时破解泛亚铁路西段云南大理至瑞丽沿线的工程地质难题,早日打通中国通往东南亚的重要战略通道,“泛亚铁路大理至瑞丽沿线地质构造综合研究”项目组在部署实施的铁路沿线22幅1∶5万区域地质调查基础上,综合编制了铁路沿线的1∶2.5万地质图和工程地质图,并从多学科的角度,系统查明和评价了铁路建设区的基础地质与工程地质条件、地质灾害类型与分布、重要断裂带的活动性及其工程影响和高黎贡山越岭段的工程稳定性等,为铁路选线、设计与施工提供了重要的地质支撑,减少了工程设计与施工方面的盲目性,并为未来铁路建设提供了重要的地质保障。此项工作开创了基础地质调查与重大工程建设需求紧密结合的新模式,被誉为地质工作服务于国家重大工程建设的典型范例。
Abstract:
For solving engineering geological problem along the Dali-Ruili segment located in western Yunnan of Pan-Asia railway network,and getting through the important strategic channel between China and southeast Asia as soon as possible,the comprehensive geological structure research team finished the 1∶25 000 geological map and engineering geological map covering the Dali-Ruili railway based on the 22 sheets 1∶50 000 geological maps from regional geological surveying work along the railway. From a multidisciplinary perspective,the team systematically identified and evaluated the basic geological and engineering geological conditions of the railway construction,the type and distribution of geological disaster,the activity of the main fault zones and their effects on railway engineering and the engineering stability of the Gaoligong Mountains section,etc..The excellent geo-logical work provides an important support and geological safe guard to the route selection,design and construction of the Dali-Ruili railway,and is helpful to reduce the blindness of railway engineering design and construction in the future.This work created a new mode on the combining basic geological survey and major engineering con-struction in China,and was known as a typical example on the basic geological work in the service of the national major projects construction.
