摘要
文章以抛石体与围岩的电阻率差异为前提,建立水下抛石工程的数学模型,利用有限单元法实现了模型的高密度电阻率法温纳装置、偶极装置、微分装置和施伦贝尔装置的正演计算,并对比分析了4种装置的反演结果。研究结果表明,温纳装置能清楚地识别探测范围内抛石体的赋存形态与结构,且可以较准确地圈定抛石体水平向的分布范围,即使用高密度电法探测水下抛石体的赋存状态具有较好的效果,为水下抛石工程的质量评价提供了重要的理论基础。
Taking the resistivity difference of the enrockment and its surrounding rock as physical premises ,a mathematical model of underwater enrockment was established .Then by using the finite element method ,the forward calculation of the established model for different types of devices such as Wenner device ,dipole device ,differential device and Schlumberger device was realized .And the in-version results of the four devices were also analyzed .The results show that the Wenner devive can delineate the form and structure of the enrockment in the detection region and its horizontal range is better than the other three devices ,which means that it is feasible to explore the form of underwater enrockment by high density resistivity method .The research results provide an important theoretical basis for evaluating the quality of underwater enrockment project .
