Tunnel Cost Model: A Stochastic Simulation Model of Hard Rock Tunneling. Volume 1. Summary Report.

摘要

This report describes the completed 1st phase in a project to develop a tunnel cost model--the organization and scope of the model;its technical content,assumptions,and capabilities;and the relation of the model to various exploratory and tunneling practices. The report consists of three volumes; a Summary Report, a Technical Report,and the Appendices. The tunnel cost model was developed in an attempt to improve the assessment of uncertainty in tunnel cost estimates,with enough detail and accuracy to aid in preparing estimates or bids. The scope of the model is limited to hard rock tunneling. A working version of the model has been obtained and trial runs of selected example problems have been run and are discussed in this report. This report is the 1st in a series relating to the tunnel cost model to document the work continuing under the research project mentioned.
