摘要:

In this article, we describe the development of an expert system (ES) for tunnel design and preent some applications of the system. The system has been developed by our research group consisting of 21 people closely involved with the tunnel design under the leadership of Nagoya University. The system consists of four subexpert systems (1) ES for standard tunnel design methods, (2) ES for framed structure method, (3) ES for theoretical design methods, and (4) ES for numerical analysis design method; a common part to control the overall system; and two data base systems (tunnel data base system and rock mass data base system).

摘要:

The paper discusses several potential civil engineering applications of inductive systems based on the theory of rough sets. This theory is discussed briefly. An inductive system is proposed for applications in knowledge acquisition for expert systems, for problem‐solving, shallow modeling, learning about different domains, and in learning expert system

摘要:

Aknowledge‐based system, whose objectives are to support the procedures which lead to the seismic risk evaluation of buildings and to suggest possible retrofitting, is presented. The system architecture and its principal functions are described, with emphasis on the main part of the system: a model (“artificial world”) which describes the structure and possible behaviors of the building and its environment, at different definition levels, with qualitative and/or quantitative attri

摘要:

The paper introduces the main measures of uncertainty and discusses some of the problems associated with conventional uncertainty propagation methods, such as those based on independent probabilities and the methods used with certainty factors, belief, and possibility functions. Some examples show the importance of the associated errors. Alternative methods, such as log‐linear regression and causal networks or influence diagram models, are discussed. Finally, their structural and parametric learning possibilities are analyze

摘要:

Data base management technology can improve the quality and reduce the cost of temporary works design. This is achieved by allowing the computer to handle the tedium of translating and transmitting data between programs and allowing the designers to concentrate on the quality of the underlying design. This paper lays the foundation for the use of microcomputer data base management technology in temporary works design, using formwork design as the problem base. It concentrates on the development of a data base management system called dBFICADS. It has been used to support the data‐handling requirements of an integrated computer‐aided design system for form‐work Key issues regarding information modeling, DBMS implementation, and the interface between the DBMS and application programs are addr

摘要:

Computer applications related to under‐ground construction are described as they are being applied to Boston's Central Artery/Third Harbor Tunnel Project. The project is currently one of the largest highway projects in the country. Computer applications include a geotechnical boring log management system, spreadsheets for tunnel analysis and design, finite‐element studies of soil‐structure interaction for a construction excavation problem, and software that draws flow nets. Each application is outlined, and problems and future improvements to the methods are disc
