The application of shallow seismic reflection in preselecting the location of a major engineering project

With a purpose to provide basic data or figures for the feasible research of a project construction and its planning, taking the practical project of preselecting a factory location for an instance, using the principle and method of shallow seismic reflection, based on the area conditions, differences in physical features and disturbance, with experiments on typical sections of the construction area, one can draw reasonable measuring lines, choose right modes of producing and receiving waves, conduct primary and precise computer data processing, acquire a distinct reflected wave section from a shallow depth and explore the stratum structure in the preselected location and the distribution of longitudinal waves. The results show this method is scientific and feasible and can bring excellent effects in practice.
