【 摘 要 】

The multichannel analysis of surface wave (MASW) has drawn considerable interest in subsoil investigation and characterization. This method has been studied and improved in the last few decades, thereby leading to several combinations of existing active and passive methods. This study aims to identify the presence of marine clay layer using combined active and passive MASW methods. The shear wave velocity profile obtained interpreting clay layer within the range of 70-150 m/s and sand layer within the range of 100-300 m/s. Results suggest that the combined MASW method significantly improves shear wave velocity profiling in shallow and deep soil layers and the results are validated using the cone resistance and shear wave velocity estimated from cone penetration test.Introduction.
