近年来,新疆水电工程建设逐渐向河流的中上游段推进。工作区的地形特征多为河谷陡切、河床狭窄曲折,地质特征多为覆盖层深厚、基岩界面起伏大,这些因素决定了浅层反射法在水电勘察工作中发挥着重要的作用。本文通过典型的工程勘察实例,介绍了浅层反射法可勘探深度大、定量解释效果好等优点,同时也指出了反射波辨识困难、处理软件功能单一的现状。
In recent years, the construction of Xinjiang hydropower gradually advances to the upper reaches of the river. Most of the topographic features in the work area are steep river valleys, narrow and tortuous riverbed, mostly geological features with thick overburden and large fluctuation of bedrock interface. These factors determine that shallow reflectometry plays an important role in hydroelectric survey. In this paper, through the typical example of engineering survey, the advantages of shallow reflection method, such as large exploration depth, good quantitative explanation and so on, are introduced. At the same time, it is also pointed out that the reflected wave is difficult to identify and the function of processing software is single.
