CASE EXAMPLES OF ROCK STABILITY ON TRANSPORTATION PROJECTS

Rock stability on transportation projects is influenced most significantly by structural geology, groundwater pressure, blasting and rock strength. Modes of failure include circular, planar, wedge. block, toppling, buckling, keyblock, ravelling and boulder fall. Numerous procedures to stabilize rock are available and described in the FHWA Rock Mitigation Manual. To illustrate a number of rock stability problems, five transportation case examples are described.
