剪切波速测试技术是一种快速准确的原位测试技术,它是通过锤击震源板获得剪切波经过不同地层时的直达波旅行时间来求取地层的剪切波速度,进而获取等效剪切波速,该技术可以为场地土的类型、建筑场地类别划分提供基础数据资料,剪切波测试技术目前广泛应用于重大工程建设、高层建筑的工程地质评价和建筑抗震设计等领域中。本文主要介绍了剪切波速测试技术的基本原理和野外实测技术,以及数据处理和资料解释全过程,并且结合某重庆城区某一建筑场地的应用实例,说明剪切波速测试技术在建筑场地抗震评价中的应用及其效果。
Shear wave velocity testing technology is a fast and accurate in situ testing technique, which obtains the shear wave velocity of strata by hammering the source board to obtain the direct wave travel time of shear waves passing through different formations, and then obtains the equivalent Shear wave velocity. This technology can provide basic data for the type of site soil and classification of construction sites. The shear wave testing technology is widely used in the fields of major engineering construction, engineering geological evaluation of high-rise buildings and seismic design of buildings. This paper mainly introduces the basic principle of shear wave velocity testing technology and the field measurement techniques, as well as the data processing and data interpretation of the whole process, and combined with a Chongqing city construction site application examples illustrate the shear wave velocity test technology in the construction site seismic evaluation In the application and its effect.
