遥感在河流谷坡工程地质环境评价中的应用

河流谷坡工程地质环境评价是水电工程的前期工作,直接关系到工程的选址、建设规模和水利资源的充分利用。 本文利用现有航空遥感资料,对四川雅砻江中游的鲜水河口至官地河段,约510 km河流谷坡的物理地质现象进行了判读,运用数理统计和工程地质综合分析的方法,对该河流区段的工程地质环境进行了评价,并对其发展趋势进行了预测,为该地区丰富的水利资源的开发利用提供了决策依据;对于区域工程地质环境评价,尤其是基础工作薄弱、自然条件恶劣、地面工作难以开展的高山峡谷地区的河流谷坡工程地质环境评价和发展趋势预测提出了新的方法。

Application Remote Sensing to Evaluate Engineering Geological Environment of River Valley

It is the basic work of the hydropower project to study the engineering geological environment of river valley, which effects the locating of project and the power of station.In this paper using aerial photos we interpret the physical geology phenomenon (including landslide, collapse and rockstack) along the valley of the Ya Longjiang River, from the Xian Shuihe River to Guandi, ranginy 510 km, in the southwest China. Utilizing the methods of mathematical statistics and engineering geology we also evaluate the engineering geological environment of this section of the river valley, predict the tendency of the development and provide decision basis for exploiting the rich water resource of this area. The way of our work in this paper has general sense for studying engineering geological environment of a region, especially in a river valley, in which the basic work is weak natural condition is adverse and the ground work is difficult.
