COMPARISON OF FULL-SCALE EMBANKMENT TESTS WITH COMPUTER SIMULATIONS-VOLUME ONE, TEST RESULTS AND COMPARISONS

SIX FULL-SCALE TESTS OF AN INSTRUMENTED AUTOMOBILE WERE CONDUCTED ON AN EMBANKMENT. THE TESTS WERE CONDUCTED FOR VARIOUS COMBINATIONS OF VEHICLE ENCROACHMENT SPEED AND ENCROACHMENT ANGLE. THE EMBANKMENT, WHICH WAS ON TEXAS STATE HIGHWAY 21, CONSISTED OF A 3.5:1 SIDE SLOPE AND A RELATIVELY FLAT BOTTOM DITCH APPROXIMATELY 20 FEET BELOW THE PAVED ROADWAY. EACH TEST WAS SIMULATED BY THE HIGHWAY-VEHICLE- OBJECT-SIMULATION-MODEL (HVOSM), A COMPUTER PROGRAM, AND THE RESULTS WERE THEN COMPARED WITH THE MEASURED TEST RESULTS. WITH THE EXCEPTION OF THE TESTS IN WHICH SUSPENSION FAILURES OCCURRED IN THE TEST CAR, THE CORRELATION BETWEEN THE MEASURED AND PREDICTED DATA WAS GOOD. VOLUME ONE DESCRIBES THE STUDY AND INCLUDES THE TEST RESULTS AND COMPARISONS. VOLUME TWO CONTAINS THE HVOSM COMPUTER INPUT AND SAMPLE OUTPUT RELATED TO THE STUDY. /FHWA/
