Abstract: This paper presents a safety assessment system for power transmission tower foundations using hierarchy process and comprehensive fuzzy judgment approach. This foundation safety evaluation system software was developed by using Microsoft VB 6.0 programming language and could automatically evaluate the safety of power transmission tower foundations. This software includes two major modules: power transmission tower foundation information management module and foundation safety evaluation module. The software has the advantages of friendly user interface, easy to operate and clear outputs. The software development strategy and algorithms are introduced and the fuzzy evaluation approaches on the input data are also applied in the system.

Key words: Power Transmission Lines, Transmission Tower Foundations, Safety Assessment System
