The Reliability Analysis of Cut Angle Fuzzy of Chimney Demolished by Controlled Blasting

Abstract:

Cut angle is one of the best important parameters of chimney demolished by controlled blasting. The suitable angle is effected by a lot of factors. But mechanical principle is not entirely clear. The theoretical value of angle is usually designed by experience formula . At the same time, the factual angle made by blasting is also fuzzy and random. So in this paper, the formula to calculate fuzzy reliability of cut angle is derived according to fuzzy reliability theory. It provides an credible parameter for engineering blasting designer. Linear memberships function is adopted for theory value of cut angle and the factual blasting angle is a random variable which is suggested to be normally distributed. At last, an engineering example is given to verify the method of this paper.
