随着高层建筑的大量涌现,大型工业建设中动力基础的不断发展以及工程抗震等方面的需要,自50年代以来,国际上就把工程地震勘探作为一种新的行之有效的勘探技术和手段,现正在工程地质、岩土工程以及地震工程的各个领域中得到广泛的应用。在我国70年代初期才逐步开展此项工作,经过十多年的实践证明,弹性波速度的测试及应用 With the rapid emergence of high-rise buildings, the continuous development of the power base in large-scale industrial construction, and the need for engineering anti-seismic and other aspects, since the 1950s, engineering seismic exploration has been used internationally as a new and effective exploration technology and means. Now it is widely used in various fields of engineering geology, geotechnical engineering and earthquake engineering. This work was gradually carried out in the early 1970s in China. After more than 10 years of practice, the test and application of elastic wave velocity was demonstrated.
