摘要
许多工程场地覆盖层薄,现有野外波速测试仪可测范围一般是≥1.0m,对于众多厚度为数十厘米的薄土层,如果只是简单地进行合并处理,则测出的波速失真多,并且难以确定这种混合层的土动力参数。为此本文提出了一种薄土层剪切波速的测试和计算方法,并在临沂市地震小区划工作中得到具体应用。
In many cases, the engineering sites are covered with thin layers. At present the measurable range of wave velocity of the apparatus applied in the field is usually more than 1.0m. For some layers with thickness of several tens centimeters, the measurable velocity might be of larger uncertainty if the thinner layers are treated with simple merge, and it is difficult to determine the soil dynamic parameters of the mixed layers. So this paper proposed a method to measure and calculte the shear wave velocity of thinner layers and it is practically used in seismic microdivision of Linyi city.
