综合勘察技术在岩土工程勘察中的应用

APPlication of Combined Survey Methods for Investigation of Geotechnical Engineering

本文介绍了某工程采用多种物探技术结合钻探手段揭示场地地层结构及其分布变化规律,尤其是碎卵石持力层的埋藏分布情况取得成功的案例。综合物探技术采用了横波反射波法、高密度电法和瞬态面波法,并介绍了方法、原理和勘察效果,以及在复杂地质条件下采用综合勘察技术提高岩土工程勘察精度的可行性。

Three geotechnical methods combied with drilling are used in the site investigation to detect the complex geological conditions and stratigraphic distribution,especially the distribution rule of cobble layer,and the results are satisfactory.The combied geotechnical methods include traverse wave reflection,high density resistivity as well as active surface wave.The principles and results of different geophysical methods are briefly introduced,and the important role of integrated survey approach are analyzed,so as to better enhance the level and quality of geotechnical investigation.
