摘　　要：目的研究陕西省高速公路设计带不良地质分布规律,为公路可行性研究提供选线依据。方法将TM图像按照TM7-TM4-TM2波段顺序合成处理,结合现有地质资料和野外调查成果,对陕西省高速公路设计带不良地质现象进行分析和评价。结果发现断层和滑坡(滑塌)、崩塌在陕西省整个区域均有分布,是影响高速公路建设的主要不良地质现象,秦巴山地不良地质密度最大,毛乌素沙漠区密度最小。结论遥感技术在分析和评价高速公路不良地质分布规律方面具有速度快、质量高、效益显著的优势。Aim To find out the phenomena of bad geology and distribution regularity of Shaanxi provincial freeway design zone, provide regional engineering geology survey in the research region on feasibility study stage. Methods The TM image is synthesized and processed with the sequence of TM7（R）-TM4（G）-TM2 （B）band. Combining the existing geology data and field survey results, the analysis and assessment of the bad geology phenomenon Shaanxi provincial freeway design zone obtained. Results Fault and slide （slump） is distributed in whole shaanxi provincial zone,it is the main effect of freeway construction, density is maximum in in Qinba mountainous area, density is minimum in Maowusu desert area, all bad phenomenon distribution feature of Shaanxi provical natural region is found out. The corresponding preventing collision and advice plan are given. Conclusion The RS technolo- gy advantage of quick speed, precise, benefit sufficient is represented.
