Abstract: For scientifically, accurately, fast, intelligently evaluating the status of engineering surrounding structure, a model component is designed and implemented for surrounding structure risk evaluation based on extension matter-element theory. From the extension matter-element mode in engineering surrounding structure risk evaluation operations, such matter-element structure and risk space are established, and risk evaluation and deflection judgment are improved for engineering surrounding, with the integrated component weight of variation coefficient and entropy information. Following the natural idea and key concepts of extension matter-element model, and focusing on the requirement of such model intelligent implementation and user visualized operation, the design scheme, system framework and function composition are advanced, and thus algorithm component is developed for engineering surrounding structure risk matter-element based on windows thread design. Case shows the good interaction of matter-element model component, which provides the effective model support and experiment tool to analyse the risk nature of engineering surrounding structure.
