THE FINITE ELEMENT TECHNIQUE WAS USED TO DEVELOP A UNIQUE COMPUTER PROGRAM FOR ANALYZING THE PERFORMANCE OF BRACED EXCAVATIONS IN TEST SECTIONS OF A CUT-AND-COVER SUBWAY. FINITE ELEMENT PROGRAMS PERMIT THE ANALYSIS OF PREVIOUSLY UNSOLVABLE PROBLEMS; ELEMENT TYPE, METHOD OF LOAD APPLICATION, ELEMENT GRID SIZE, AND INPUT MATERIAL PROPERTIES ARE A FEW OF THE VARIABLES WHICH DETERMINE THE ACCURACY OF SIMULATIONS USING THIS METHOD. THE REPORT EXAMINES SEVEN LIMITATIONS AND PROBLEMS OF THE LATEST VERSION OF THE PROGRAM, CALLED BRACE II. A COMPLETE PRINTOUT OF THE BRACED EXCAVATION ANALYSIS IS PROVIDED. /UMTA/
