Introduction

There is a growing awareness within the geotechnical and environmental community that cone penetrometer technology (CPT) offers the fastest and most economical way to characterize the subsurface conditions of most sites. CPT probes provide a continuous profile of the underlying site stratigraphy and when combined with environmental probes and field or lab analysis of CPT extracted soil, water, and gas samples can provide a detailed three dimensional view of any subsurface environmental contamination.

Truck Specifications

As part of its research instrumentation, the Center for Geotechnical and Environmental Research (CGER) at Ohio University has a 25 ton CPT truck. Characteristics of the CPT and Peripherals are described below:

• The Truck has a push frame capable of exerting more than 25 Tons of pushing or pulling load on cone rods.
• The Hydraulic Cone Rod Clamp is capable of gripping cone rods of 1.4 through 1.75 inches in diameter.
• Hydraulic cone circuit is capable of 28 G.P.M. at 3000 psi.
• The system has the capability of penetrating down to 200 feet.
• A 6 inch coring drill is available as a peripheral.
• The unit has the capability of generating up to 7500W of electrical power.
• Automatic Seismic Hammer.
• Data Acquisition System with Real Time Display and Analysis Software.
• Data from Geophones and Shear Hammer can be used to calculate:
  • Shear Modulus vs Depth
  • Youngs Modulus vs Depth
  • Poisson's Ratio vs Depth
