随着我国水利水电建设的发展,作为直接取得地下地质实物资料和为地下岩体力学测试、物探测井、水文地质测试及基础处理等创造技术条件的唯一手段的钻探,有了较大的发展,特别是近些年来发展更为迅速,主要表现在设备和技术已初步实现更新,更先进的技术方法已开始研究应用,因而促进了钻探质量的不断提高和生产效率的成倍增长。下面拟扼要谈谈我国水利水电工程地质钻探技术的现状,并对今后如何改进钻探工作提出几点意见和建议。
With the development of China’s water conservancy and hydropower construction, there has been a great development as a direct means of obtaining underground geological materials and the only means of creating technical conditions for mechanics testing, geophysical logging, hydrogeological testing and foundation treatment of underground rock masses In recent years, the development has been more rapid. The main achievements have been the initial updating of equipment and technologies. The application of more advanced technological methods has started to be studied, thus promoting the continuous improvement of drilling quality and the doubling of production efficiency. The following is a brief talk about the current status of geological drilling technology for water conservancy and hydropower projects in China, and put forward some suggestions on how to improve drilling in the future.
