地球物理勘探在堤防隐患探测中的应用

Application of Geophysical Exploration in Embankment Hidden Danger Detection

2021年受台风“烟花”影响,新沂市某大堤右堤经历了连续多天暴雨天气,堤防遭受持续的雨水冲刷,在大堤右堤某处发现堤顶迎水堤肩存在少量纵向裂缝。为确保堤防的安全,文章采用地质雷达、高密度电阻率相结合的方法进行地下探测工作。地质雷达法和高密度电阻率法都属于地球物理勘探的方法,两种方法各有优缺点,应用时应坚持扬长避短,互为补充的原则,综合分析探测成果,查明裂缝产生原因。

In 2021,affected by typhoon "fireworks",the right embankment of a levee in Xinyi City experienced several consecutive days of heavy rain weather,and the levee was washed by continuous rain,and a small number of longitudinal cracks were found on the shoulder of the levee top.In order to ensure the safety of the levee,the paper adopts the method of geological radar and high density resistivity to carry out underground detection.The geological radar method and the high-density resistivity method belong to the geophysical exploration methods,each of which has its own advantages and disadvantages.The principle of complementing each other should be adhered to in application,and the detection results should be comprehensively analyzed to find out the causes of cracks.
