Abstract
A new s-wave probe, called "MudFork", has been recently developed and is used in accurate measurements of shear wave velocities of soft soils. In previous researches, some instrumental defects of the probe have been reported. Bending deformation of probe is caused by small section modulus of blades, and open-ended bender elements are vulnerable to damage during penetration. Herein, we improved the MudFork to solve these problems. Field tests at Sinan, Jeollanamdo using the improved MudFork were conducted. Results from MPT are compared with the results from CPT.
