Abstract

Werka descent road lies at western region of Saudi Arabia. It is constructed two years ago harmed due to rainstorm and absence of remedial measures. Werka mountainous road subjected to failures of man-made rock slope faces, and debris flow along both sides of 8-m width road. Intensive geotechnical study includes the RMR and GSI rock masses classifications were applied indicates that the rocks are medium to poor quality. The integrated techniques such as graphical method, modeling, and simulation were utilized to assess rock slope failures and rockfalls by using DIPS, RocFall, RocPlane and Swedge programs, and recommend the remedial measures for failures. The seismic coefficients of 0.1 to 0.4 were taken into consideration in modeling. Debris flows from higher elevation were a result of the poor rock quality. A manmade slope cut were studied and modeled utilizing the integrated techniques. The analyses indicate that the intensity of rainfall, joints set attitudes with the slope face attitude, Jv, block size, block shape, specific gravity, coefficients of restitution and the slope geometry are the main factors in rock slope failure, rockfall and debris flows problems.

Failures and Remediation of Rock Slope Stability Problems and Remediation at Earthquakes at Part of Werka Descent Road West of Saudi Arabia

Chicago, Illinois

Werka descent road lies at western region of Saudi Arabia. It is constructed two years ago harmed due to rainstorm and absence of remedial measures. Werka mountainous road subjected to failures of man-made rock slope faces, and debris flow along both sides of 8-m width road. Intensive geotechnical study includes the RMR and GSI rock masses classifications were applied indicates that the rocks are medium to poor quality. The integrated techniques such as graphical method, modeling, and simulation were utilized to assess rock slope failures and rockfalls by using DIPS, RocFall, RocPlane and Swedge programs, and recommend the remedial measures for failures. The seismic coefficients of 0.1 to 0.4 were taken into consideration in modeling. Debris flows from higher elevation were a result of the poor rock quality.
