摘要
均质土坝在堤坝建设中应用比较常见,在长时间运行与使用后,由于各种外界和内在因素的原因,坝顶和坝坡道路会产生裂缝,若不进行处理,会使堤坝运行安全隐患大大增加。地质雷达技术属于工程物探方面一种新型检测仪器和技术,该方法具有工作效率高、分辨率高和异常图象直观等突出优点,因此,该方法广泛应用于工程勘察中。文中利用地质雷达技术,对某大坝坝体裂缝进行探测,较准确地推断出工程隐患的性质和位置,从而便于以后更好的指导工程施工处理。
A homogeneous earth dam is applied are commonly in the construction of a dam,after long-term operation and use,on the road of dam crest and dam slope some cracks will appear partly due to variety of external and internal factors. The safety hidden danger of dam operation will be greatly increased if not handled. Geological radar technology is a new type of engineering geophysical detection equipment and technology,this method has many outstanding advantages such as high efficiency,high resolution,abnormal image intuitive,etc,therefore,this method is widely used in engineering investigation. In this paper,the geological radar technology is used to detect the cracks of a dam,so as to accurately infer the nature and location of the project risk,in order to better guide the construction of the project.
