ABSTRACT: This paper presents the design and development of a package, based on Monte Carlo simulation techniques, that can model the operation of mechanized underground excavation systems. The primary use of the package is to estimate time and cost required to complete a given tunnel, in addition to predicting equipment utilization. A data base containing performance records from more than 450 tunnel boring machine (TBM) projects is used to derive a ground classification system, predictive equations for various performance parameters, and probability density functions of various components of mechanized underground excavation systems. Analysis of various possible excavation system configurations is achieved by using rate of failure and delay information for each comprising subsystem. The estimation of time to complete a given tunneling project can be done in different ways depending on available project information.
