Abstract : The Multi-Channel Method for Surface Waves (MASW) was used to measure the average velocity of shear waves in order to construct an engineering structure and its relationship to bearing capacity, foundation depth and soil thickness in this construct in the center of Hilla city.) Active MASW) was used in this study which allows us to measure the apparent dispersion curve or the phase velocity within the frequency range (5-70) Hz, which gives information about the shallow layers (25-50 m) and depen
