Evaluation of frequency effects on in-situ measurements of shear wave velocities using the cone penetration surface wave methods

地球物理方法很容易用于地震场地表征，在加拿大公路桥梁设计规范（CHBDC）的地震规范最近发生变化后，这在加拿大变得越来越重要。研究激励频率对地球物理测试结果精度的影响对于正确评价原位特性是非常重要的，因为不适当的激励频率可能会遗漏关于薄土层和透镜体的信息并给出错误的结果。

Geophysical methods are readily used for seismic site characterization, which is becoming increasingly important in Canada after the recent changes in the seismic specifications of the Canadian Highway Bridge Design Code (CHBDC). Investigating the effect of frequency of excitation on the accuracy of geophysical test results is very important for the correct evaluation of in-situ properties because improper excitation frequency may miss information about thin soil layers and lenses and give erroneous results.
