The basic structure of the probe, called “MudFork", is a fork composed of two blades, on each of which source and receiver bender elements were mounted respectively. Much effort was exerted to reduce noise transmitted through the frame from the source to the receiver bender, cross-talk caused by high voltage driving the source bender and coating of the elements against salty water. The prototype probe has been developed through extensive in-house program to optimize in terms of data quality and installation convenience. The first prototype probe was penetrated in coastal mud using SPT(standard penetration test)rods pushed with a routine boring machine and shear waves signals were measured. The shear wave signals were so excellent that the first arrival time can be easily identified. The shear wave velocity profile was validated with the laboratory measurements of shear wave velocities of specimens sampled.
