水电钻探的目的是要查明各主要水工建筑物基础的工程地质条件,特别是要查明岩层的产状、构造、岩性、风化深度、渗透性与稳定性等特性,以及岩溶和软弱夹层的分布特点与发育规律等重大地质问题。所有这些地质资料的取得,当前在很大程度上要依赖于钻探岩心的质量,只有在取得高质量岩心的基础上,才有可能全面、彻底、准确、可靠地查明上述的工程地质特性。然而,我们钻探工作的现状和
The purpose of hydroelectric drilling is to identify the engineering geological conditions of the foundation of each major hydraulic structure, especially to find out the characteristics such as rock formation occurrence, structure, lithology, weathering depth, permeability and stability, as well as karst and weakness Mezzanine distribution characteristics and development law and other major geological problems. All of these geological data are currently being obtained to a large extent dependent on the quality of the drilling core, and it is only possible to fully, thoroughly, accurately and reliably ascertain the above-mentioned characteristics of the engineering geology on the basis of obtaining high quality cores. However, we are drilling the status quo and work
