Design of a Pseudo-Interval Autonomous SCPT System

摘要

Seismic cone penetration testing (SCPT) is a geotechnical tool which allows for the determination of low strain (< 10(-4)%) in situ compression (V-P) and shear (V-S) wave velocities. Among in situ engineers, there is considerable interest in the development and advancement of SCPT systems, which operate autonomously without any user interaction aside from initial start-up. This technical note outlined such a system (a pseudo-interval autonomous SCPT system), and covered in detail the autonomous sensor based data triggering algorithm, which is an essential element of an autonomous system that can be used both onshore as well as offshore.
