Testing piles with virtual instruments
Erez I. Amir & Joram M. Amir

Since its introduction to the piling community, pile-testing equipment has developed through three generations: 1. Purely analog (Oscilloscope) equipment, 2. Digital systems based on purpose-built computers and proprietary operating systems, 3. Systems based on ruggedized laptop PC computers with DOS based software. Today, practically all testing systems in use are digital, belonging to either second or third generation. This paper describes the principles of fourth-generation testing equipment that has recently become available. Consisting of existing off-the-shelf resources, such as notebook computers and WINDOWS operating system, it utilizes the accelerated progress made in computing power, peripherals and software capabilities. As an illustration, the paper describes two fourth-generation systems for the integrity testing of piles: The Pile Echo Tester (PET) and the Cross Hole Ultrasonic Monitor (CHUM).
