APPLICATIONS OF PENETRATION TESTS FOR GEO-ENVIRONMENTAL PURPOSES

The application of penetration tests for geo-environmental purposes has grown rapidly in recent years. The Cone Penetration Test (CPT) has become recognized as a valuable in-situ testing technique because of its speed, reliability, cost effectiveness and excellent soil profiling capabilities. In recent years additional sensors have been added to the CPT equipment to enhance and expand its capabilities for environmental purposes. These additional sensors include electrical resistivity/conductivity and permittivity measurements, pH and ion detectors as well as special fiber optic devices for fluorescence measurements. Special penetrometer sampling probes have also been developed to obtain liquid and/or vapor samples as well as soil samples. These sample probes are installed with CPT equipment and vary from simple inexpensive devices for bulk water samples to sophisticated probes for very high quality water and/or vapor samples from specific zones. These sample zones are often identified using the continuous profiles from CPT equipment with special sensors. A summary of recent advances in CPT and penetrometer equipment related to geo-environmental applications is presented and examples are shown to illustrate these applications.
