| 摘 要： | 波速测试技术是地震勘探方法之一,也是一种简便、快速、准确的原位测试技术。它通过获取的地震波在经过不同深度的岩、土层的直达波旅行时,求得纵波、剪切波波速,进而通过弹性波理论,计算出岩、土层动弹性力学参数,同时也可以根据剪切波的波速,来划分场地土类型和建筑场地类别,以及计算卓越周期,这些参数可以为场地抗震设计及地震安全性评价提供依据。这里简述了波速测试技术的工作原理和野外实测技术,以及数据处理和资料解释全过程,并且结合某一建筑场地的实例,说明了波速测试技术在场地抗震评价中的应用及其效果。

| Abstract: | Wave-velocity test technique is one of seismic exploration methods.It is an easy,rapid and accurate method of in-site measurement.The velocities of P and Shearing-wave may be obtained by measuring the travel time of first break from seismic wave field propagated through rock and soil at different depths.Furthermore,some kinetic parameters of rock and soil may be figured out according to the velocities of P-wave and S-wave based on elastic theory,meanwhile,the site soil type and building site category can be... |
