摘　　要：随着人类社会的高速发展和工程建设的激增,地质环境扰动日益显著,极端气候因素影响日益增多,地质灾害日益频繁发生,对人类的威胁和造成的损失也随之日益加剧。滑坡是其中最主要的地质灾害,因此,研究滑坡发育、发展、发生整个地质过程中伴随的物理现象,研究其信号特征,从而间接获取滑坡发展变化的过程是地质灾害探测或监测的基础性研究,是值得深入探索的科学问题。但是专门用于滑坡探测的电磁仪器关键设计及具体实现的研究尚较缺乏。本研究以电子电路学、嵌入式计算机科学、数字信号处理技术、地球物理以及工程地质等多学科交叉的理论体系为基础,自主研发能用于滑坡探测电磁探测仪功能样机。本设计结合当前电子学科发展水平,将嵌入式多核达芬奇结构工业级计算机系统应用在地球探测仪器领域中,设计并实现了拥有自主知识产权的应用于滑坡探测的关键设备。若进一步完善并市场化,或可解决我国滑坡工程地质灾害监测领域业高端电磁仪器严重依赖进口的难题,可为滑坡不良地质勘察及防护提供强有力的技术支撑。With the rapid development of human society and the surge of engineering construction,the disturbance of the geological environment has grown substantial.The infl uence of extreme climatic factors and the frequency of geological disasters have increased.Landslide is an important geological disaster.The foundational research in geological disaster detection or monitoring involves studying the physical phenomena associated with the occurrence of landslides,analyzing their signal characteristics,and indirectly determining their development and changes.This scientifi c area is worthy of in-depth exploration.However,research on the key design and specific implementation of electromagnetic instruments tailored for landslide detection remains lacking.This study is based on the interdisciplinary theoretical system of electronic circuits,embedded computer science,digital signal processing technology,geophysics,and engineering geology.It independently develops a functional prototype of an electromagnetic detector for landslide detection.This design combines the current level of development of electronic disciplines and applies the embedded multicore Da Vinci industrial-grade computer system in the field of earth detection instruments.This study then designs and implements a landslide detection system with independent intellectual property rights.
