A SURVEY OF EARTH SLOPE FAILURES AND REMEDIAL MEASURES IN TEXAS
THE RESULTS OF A SURVEY UNDERTAKEN TO IDENTIFY REGIONS IN TEXAS WHERE THERE HAS BEEN A HIGH INCIDENT RATE OF SLOPE FAILURE AND TO IDENTIFY SOME OF THE FACTORS RESPONSIBLE FOR THESE SLIDES ARE PRESENTED. IN CONJUNCTION WITH THIS STUDY A REVIEW OF PRESENT SLOPE DESIGN PROCEDURES AND THE REMEDIAL MEASURES EMPLOYED BY THE TEXAS HIGHWAY DEPARTMENT FOR REPAIR AND MAINTENANCE OF EARTH SLOPES IS CONTAINED IN THIS REPORT. THE MAJOR SLOPE FAILURES OF SIGNIFICANCE WERE FOUND TO BE ASSOCIATED WITH PRIMARILY EXCAVATED (CUT) SLOPES IN STIFF-FISSURED CLAYS AND CLAY SHALES, ALTHOUGH FAILURES IN EMBANKMENT (FILL) SLOPES CONSTRUCTED OF HIGH PLASTICITY CLAYS WERE ALSO ENCOUNTERED IN SEVERAL AREAS. A NUMBER OF REMEDIAL MEASURES HAVE BEEN EMPLOYED FOR REPAIR OF THESE FAILURES, INCLUDING REGRADING, STABILIZATION WITH LIME AND CEMENT ADDITIVES, AND VARIOUS FORMS OF RESTRAINT OR BUTTRESSING STRUCTURES. WHILE EXCESSIVE AMOUNTS OF GROUND AND SURFACE WATER WERE USUALLY PRESENT AT MOST SITES WHERE SLOPE FAILURES HAVE OCCURRED, DRAINAGE OF WATER HAS NOT BEEN EXTENSIVELY EMPLOYED AS A REMEDIAL OR PREVENTATIVE MEASURE. /NTIS/
