M.I.T. TEST SECTION INSTRUMENTATION. MASSACHUSETTS BAY TRANSPORTATION AUTHORITY, HAYMARKET-NORTH EXTENSION. ADDENDUM TO FINAL PROJECT REPORT

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 constructed by the Massachusetts Bay Transportation Authority. 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 2. A complete printout of the braced excavation analysis is provided. This report was generated as an addendum to the final report of MASS-MTD-2 in which development and application of the program is covered in greater detail.
