区域性活动断裂带对高速公路路线方案的影响与控制——以康定新都桥至炉霍高速公路为例

THE IMPACTS AND CONTROL OF REGIONAL ACTIVE FAULT ON THE EXPRESSWAY ROUTE PLAN——TAKING THE XINGDUQIAO-LUHUO EXPRESSWAY AS AN EXAMPLE

康定至炉霍公路走廊沿鲜水河活动断裂带展布,断层活动造成区域地形地质条件非常复杂:地震频发、山地灾害多发,路线方案的合理布设事关项目成败。本文通过系统地搜集、整理和分析前人成果,研究论述了区域宏观构造格架、鲜水河断裂带及活动性、山地灾害等内外动力地质作用特征及相关的重大工程地质问题,在此基础上分析了断裂活动对路线方案的影响与控制作用,提出了路线方案的宏观思路见解和地震、地质灾害的专题研究建议。为路线方案设计及行业工程技术人员提供参考。

The only highway corridor from Kangding to Luhuo is distributed along the active fault along the Xianshuihe river. The fault activity leads to very complex topographic and geological conditions: frequent earthquakes, frequent mountain disasters, and the reasonable layout of route plan is critical to the success or failure of the project. In this paper, through systematically collecting, sorting and analyzing predecessors' achievements, the research discusses the regional macro structural framework, fresh water river fault zone and active, mountain hazards, such as internal and external dynamic geological processes and related characteristics of the major engineering geological problems. on the basis of analyzing the influence of fault activities of route schemes and control function, put forward the great idea of route plan and seismic, geological disaster research proposals. For the route design and industry engineering and technical personnel to provide reference.
