随着城市建设桩基施工技术的提高及计算机技术的发展，1970年美国最先将动测技术应用于工程实际，到现在已近用年，应用比较好的国家有美国、荷兰。我国动测技术应用只有十几年，但随着改革开放步伐的加快，发展很快。80年代初期地矿系统的有些单位将美国产的地震仪用于基桩动
With the improvement of construction techniques for pile foundations in urban construction and the development of computer technology, in the United States, the United States first applied dynamic measurement technology to engineering practice in 1970. It has been used for nearly a year now, and the countries with relatively good applications are the United States and the Netherlands. The application of China’s motion measurement technology was only a dozen years ago, but with the acceleration of the pace of reform and opening up, it has developed rapidly. Some units of the geologic system in the early 1980s used US-made seismographs for foundation movements.
