摘要

In recent years,the complexity of construction projects has forced project managers to develop better planning control techniques. Tunnels present serious problems due to the presence of high uncertainty and risk in their construction. This report describes the development of a project planning and control system (PCS) for tunneling. The approach taken follows the methodology used in information systems of the type used in the manufacturing and service industries. A review of the current trends in the information systems field and a survey of a group of possible users (tunneling managers) were made and the resulting information used as a background for the development of the system. Existing systems developed for tunnel applications were reviewed to determine whether they could be incorporated into the proposed system. From the systems surveyed,the Tunnel Cost Model presents an adequate approach. The development is geared at improving the areas in which the existing system lacked flexibility. Improvements were made in the simulation of construction operations and in the project scheduling capabilities. A case study is included demonstrating the use of the options developed in the planning of the construction operations and the overall tunnel.
