宁武高速公路断裂构造遥感解译与评价研究
|
摘要
根据断裂构造的遥感解译标志,对宁武高速公路兴田互通—武夷山分水关段的断裂构造进行解译和分析,发现与所推荐的高速公路线路相交的大型断裂带5条,小型断裂28条;结合初测验证资料,确定了断裂构造对道路工程稳定性影响的评价指标,并以此分析、评价该线路走廊带NE、NEE向及NW向断层对推荐线路的具体影响。研究结果表明,评价指标可为路线的选择、道路的施工提供定量化参数,提高对断裂构造的认定。
Based on remote sensing interpretation symbols of faults,the authors interpreted and analyzed all faults along the Xintian Junction to Wuyishan Fenshuiguan segment of the Ningwu Superhighway.There are 5 large fault zones and 28 small-sized faults near the proposed superhighway route.In combination with the preliminary verification data,this paper established the evaluation indexes for faults affecting the stability of the route,so as to analyze and evaluate the specific impact of NE-,NEE-and NW-trending faults in the corridor belt on the proposed route.The results show that the evaluation indexes can improve the recognition of faults and provide quantitative parameters for route selection and road construction.
