Empirical analysis of constructional quality of concrete structures in rural house based on AHP and fuzzy comprehensive evaluation
The assessment of the basic idea and technical details about the constructional quality of concrete structures in rural house based on the AHP and fuzzy comprehensive evaluation method are discussed. The assessment level system are designed according to the reference named the state standard “Code for acceptance of constructional quality of structures in rural house” which is compiling. Delphi-method, analytic hierarchy process and fuzzy comprehensive evaluation method are comprehensively utilized. The awareness and satisfaction in quality of the concrete structures in rural house about the managers and farmers are revealed. The satisfaction degree of the constructional quality of concrete structures in rural house belongs to the average. Concrete quality inspection, Concrete preparation and concrete casting should be focused on in the improvement process of constructional quality of concrete structures in rural house.
Multi-source information fusion technique for pre-estimation on landslide in highway engineering
In highway engineering, pre-estimation on the global stability of highway slopes is a key to construction design and safety. The factors on slope stability include geological data, hydrographic data, situation of slopes, the way of cut, and so on. Therefore, a suitable analytical methodology of system engineering integrating the comprehensive qualitative and quantitative information is needed. A multi-level model of fuzzy comprehensive evaluation, which is able to evaluate comprehensively the global stability of highway slope, is proposed by using multi-source information fusion technique. The qualitative grade and quantitative degree for the global stability of highway slopes is obtained by synthesizing references. Analytic Hierarchy Process method has been used to compute the subjective weights of evaluation indexes. The model is also used in a highway slope in Henan Province. The results have shown that for the highway slope, its grade and degree of global stability are IV and in mid-danger respectively. So the slope must be reinforced during construction. The example has shown that the proposed method is feasible and effective.
Extraction of comprehensive information of landslide with the fusion technique of multi-sensor and multi-model
Multiple monitoring stations are always allocated in the different parts of the same landslide when large-scale landslide is monitored in order to master and control its deformation information.But only one monitoring series can be used for only one time by the present predictive and forecasting models.In order to make use of monitoring information of the individual monitoring-station of the landslide,the mathematical method making use of multi-sensor and multi-model fusion technique to extract the comprehensive monitoring information of landslide from the monitoring series in this article is presented.
