LAND SLIDES ON THE TIJUANA-ENSENADA MOTORWAY
DESLIZAMIENTOS EN LA AUTOPISTA TIJUANA-ENSENADA AUTOPISTA TIJUANA-ENSENADA
THIS REPORT PRESENTS RESULTS AND CONCLUSIONS OF OBSERVATIONS ON THE BEHAVIOUR OF SEVEN LANDSLIDES BETWEEN KILOMETRE 12 AND KILOMETRE 21 ON THE TIJUANA-ENSENADA MOTORWAY. THE OBSERVATIONS WERE CARRIED OUT OVER A PERIOD OF 22 MONTHS (AUGUST 1967 TO JUNE 1969). THE UNSTABLE REGION RUNS ACROSS A ZONE OF SLOPES WHICH REST ON SHALE, SANDSTONE AND CONGLOMERATE, IN WHICH LANDSLIDES OCCURRED PREVIOUSLY. IT IS PARALLEL TO THE SEA SHORE WHERE EROSION TAKES PLACE. THE SEVEN LANDSLIDES WHICH OCCURRED ARE GRAPHICALLY SHOWN; THREE OTHER FAILURES WERE OBSERVED DURING CONSTRUCTION. STUDY FINDINGS SHOWED THAT THESE SLIDES MUST HAVE BEEN MAINLY CAUSED BY THE REACTIVATION OF OLD LANDSLIDES DUE TO THE WEIGHT OF THE EMBANKMENTS BUILT ON THE SLOPE AND TO THE SEEPAGE OF RAIN WATER IN THE UNSTABLE MASS. DETAILS ARE GIVEN OF THE BEHAVIOUR OF THE ROAD PRIOR TO THE SLIDES, GEOLOGICAL CONDITIONS, OBSERVATIONS AND MEASUREMENTS TAKEN, AND GENERAL CONCLUSIONS.
