Good Agreement

The effect of natural slope stability due to the tunnel excavation in mountainous areas is studied used influence function method, and one tunnel excavation project in Hebei province was analyzed, the theoretical results obtained are in good agreement with the real monitoring data, therefore, the influence function method can be effectively used to predict the ground displacement caused by tunnel excavation in mountainous area, which could provide the basis for the evaluation of the safety of such works.

Element Variation

In order to obtain the best position of mid-roll shift, this paper studies the effect of different mid-roll shift position on the strip flatness of CVC 6-H mill. Strip element variation method and influence function method are put forward to analyze the effect of mid-roll shift on strip flatness. The results show the CVC 6-H mill is able to get good strip shape. The best shift position is obtained from the calculation results. The conclusion has a good significance for the practical application.

Flatness Measurement

In flatness measurement system, the flatness measuring signal can be affected by the flatness roll deflection. The flatness roll stress was analyzed and the flatness roll deflection model was obtained by using the influence function method in this paper. The model has been developed based on the deformation of flatness roll in rolling and compensating curve has been obtained. The results indicated that the setting curve of flatness is preferably accordant with the curve of online measuring flatness, and good strip flatness can be obtained.

Vertical Displacements

Theextraction of ore and minerals by underground mining may induce groundsubsidence phenomena. These phenomena produce several types of ground movement likehorizontal and vertical displacements, ground curvature and horizontal groundstrain at the surface, and associated building damage in urban regions. Theinfluence function is a well-known and efficient method for the prediction ofthese movements, but its application is restricted to mining configurationswith the same influence angle around the mine. However, this angle may displaydifferent values when the mine is not horizontal or when other subsidenceevents already occurred near the considered mine.In this paper a methodology and analgorithm are developed, based on the traditional influence function method inorder to take into account different influence angles. This methodology isimplemented in the Mathematicasoftware and a case study is presented with data from the Lorraine iron minefield in France. Ground movements calculated with the developed methodologyshow a fair concordance with observed data.
