摘要
我国河流众多，堤防较长，且大都建于５０年代，已运行４０多年，隐患较多。对所建堤坝质量怎样快速、准确、无损伤地查出隐患，并对质量作出评价？是目前需要解决的课题。地球物理勘探以其具有快速、准确、无损伤的特点，从作为钻探和人工探视的辅助手段而成为主要手段，但把物探方法用在堤坝隐患探测尤其是堤（坝）身隐患探测方面介绍的工程实例较少，且各种物探仪器各有所长。笔者通过工程实践及自己的心得，简单介绍了堤坝隐患探测的方法。
There are mane rivers in our country. The dykes are long and they were built in the fifties and have run for more than 40 years. thus. hidden dangers exist. Fast, accurate, and nondestructive detection of hidden dangers is a problem that needs to be solved. Geophysical exploration has fast, accurate, and nondestructive characteristics. It has changed from a supplementary means in drilling and artificial exploring to the main means. But the application of the geophysical method to dam hidden danger detection is rare. And various kinds of geophysical instruments have their own advantages. The author introduces the methods of dyke and dam hidden danger detection.
