CW Microwave Location of Voids Beneath Paved Areas
The problem of locating voids beneath paved areas is a perplexing and costly one. Usually voids are investigated by test borings, which is a discontinuous hit-or-miss process. The use...

Vadose Zone Permeability Tests: Summary
Solutions to determine saturated hydraulic above a water table by means of constant head borehole infiltration tests are summarized and critiqued. Analytical solutions are available for...

Vadose Zone Permeability Tests: Steady State Results
Free surface and saturated-unsaturated flow models are applied to the problem of constant head borehole infiltrat1on tests for determining saturated hydraulic conductivity above a water...

Thompson Run Bridge Distresses: An Investigation
The failure of a pile-supported four lane highway bridge abutment overlying a 100-ft-high fill embankment was investigated. Subsurface data from the original bridge foundation design investigation...

Geotechnical Applications of Borehole Geophysics
Miniaturization of instrumentation has opened up the use of borehole geophysical techniques to geotechnical consultants, but most are not yet acquainted with the capabilities of the procedures....

Drilled Piers and Caissons
Drilled piers, also called drilled caissons, drilled shafts, bored piles, and cast-in-situ piles, have recently undergone a period of growth in their use as foundation bearing elements,...

Self-Boring Pressuremeter Study of San Francisco Bay Mud
In the early 1970's a self-boring capability was added to the pressuremeter by workers in England and France in order to reduce disturbance effects during the insertion of the pressuremeter...

Cross-Borehole Observation of Soil Grouting
An investigation of the dispersion of chemical grout injected into a sandpit experimental site near Friendship Airport, Baltimore, Md. was carried out by Lawrence Livermore Laboratory...

Self-Boring Pressuremeter Tests in Clay
The development of the pressuremeter has been impeded by two main issues evaluation of the effects if disturbance during drilling on the test data, and how to interpret engineering parameters...
