综合物探方法在南水北调西线工程中的应用
|
摘要
在南水北调西线工程中 ,拦水坝和线路的覆盖层厚度变化大 ,岩层风化带及隐伏构造的发育情况复杂 ,必须综合运用地震波法和直流电法来提高资料的解释精度和成果的可靠性 ,实际坝址的勘察结果表明综合物探方法在解决横向和竖向变化的地质问题 (物性差异 )时有着不可替代的优越性 ,而且具有方便、经济、快捷和成果直观等特点
The overlay thickness under barrage and surveying line in the west route of South-to-North water transferring project varies greatly. Weathered layer and buried structure grow complicatedly, so it’s necessary to use seismic prospecting and direct current prospecting to improve the precision in explanation and the result reliability. The result of site investigation showed that comprehensive geophysical survey has obvious advantages in resolving the geologic problem or physical property difference with transverse and vertical change. This method is convenient,economical,fast and the result is perceivable.
