Based on the massive epicontinental seas project earthquake actual material, the qualitative analysis when carried on the seabed soil layer investigation using the reflected wave, seabed sandy soil, clay, yuni soil and so on different type and different natural condition soil layer reflected wave compressional wave velocity change rule and influence factor. Based on the influence reflected wave dissemination characteristic rationale, in the contrast analysis different earth room the physical mechanics parameter test result and the reflected wave characteristic correspondence relations, has determined the influence different soil layer reflected wave characteristic primary factor. The research conclusion has the instruction significance regarding the explanation earthquake actual material.

For a shallow sea engineering earthquake measured data analysis using reflection wave seabed soil surveys, submarine sandy soil, clay, silt and other territories of the different types of soil and different from the reflection wave longitudinal wave speed changes and factors. Reflection on the impact of the wave propagation characteristics of the theoretical basis, comparison and analysis of different soil mechanics parameters indoor physical characteristics of the test results and corresponding wave reflection, the impact of different layers to determine wave characteristics reflection of the main factors. Research findings to the interpretation of seismic data is validated guidance.
