横波速度由于更能直接反映岩石的物理性质,从而在许多工程、环境和地下水勘查中有重要作用。多道面波分析方法(MASW)是一种新技术,通过求得的一维近地表横波速度剖面构建一个二维横波速度场,从而准确探测近地表介质情况。针对该方法数据的采集,提出了一种检波器排列自动安置的技术(自动安置排列),即使用牵引车辆的液压驱动装置在几秒内自动安置几十个检波器,并将其与传统安置排列的方法做了比较,结果表明,自动安置排列技术可用于多道面波分析方法,而且可以大大减少多道面波分析方法的采集时间和费用。
S-wave velocity plays an important role in many engineering, environmental and groundwater surveys because it reflects the physical properties of rocks more directly. Multi-faceted wave analysis (MASW) is a new technique that builds a two-dimensional shear-wave velocity field through one-dimensional subsurface acquired S-wave velocity profile to accurately detect the near-surface media. Aiming at the data collection of this method, a technique of automatically arranging geophones (automatic placement arrangement) is proposed. That is, dozens of geophones are automatically placed in a few seconds by a hydraulic drive device of a towing vehicle and compared with the traditional placement The results show that the automatic placement technology can be applied to the multi-surface wave analysis method, and the collection time and cost of the multi-surface wave analysis method can be greatly reduced.
