Abstract
The elucidation of the issue of waves propagating through the ground is very important in the area of seismic engineering. This requires the further development of a model experimental method effective for the clarification of a phenomenon of wave propagation. In the past, the use of low-elastic material to make a ground model made it possible to reduce the velocity of propagating waves, resulting in an easier execution of experiments. This paper discusses that in addition to an analogic method of recording used in the past, we introduced a digital method of recording to analyze quickly and accurately the phenomenon of waves propagating through a model ground. An example is given to prove the validity of the proposed method through investigation of the phenomenon of waves propagating through the ground in case there is a trench in an elastic layer lying over a rigid substratum.
