摘要
堤防隐患探测对维护水利工程安全运行,提高堤防抗洪能力具有重要意义,物探检测法是堤防隐患无损探测的最佳方法。从堤防隐患的电导率、介电常数、速度等地球物理参数出发,归纳当前隐患探测常用的物探方法,详述相应的技术理论、发展现状、适用性和局限性。提出未来堤防隐患物探技术应加强隐患物性特征分析;重视隐患物探方法的正反演理论研究;引进三维地球物理探测,提高隐患探测精度;建立多种物探方法与地质、钻探等手段相结合的综合探测方法;研究堤防时移物探技术,监测隐患发展动态;促进物探成果信息化等。
Detecting hidden troubles of embankment is of great significance for maintaining the safe operation of water conservancy project and improving the dam’s flood control ability.Geophysical method is the preferred method for nondestructive detection of hidden dam troubles.In this paper,commonly used detection methods are summarized in aspects of conductivity,permittivity,velocity,and other geophysical parameters;and the technological theories,development status,applicability and limitations are expounded.Some suggestions are also put forward for future researches:to enhance the analysis of physical characteristics of hidden troubles;to pay focus on theories of forward and inversion analysis;to incorporate 3D geophysical detection to ameliorate precision;to build a comprehensive exploration method combining various geophysical methods with geological and drilling methods;to apply time-shifted detection technology to tracing the development trend of hidden troubles;and to informatize the detection results.
