- Abstract
Based on the BP algorithm of artificial neural network (ANN), an intelligent model which is used to predict the anchorage force of soil anchor rods is established in this article, under the comprehensive consideration of the anchor rod diameter, strength of the grouting body, length of anchoring segment, bore diameter, inclination angle of the anchor rod, and other factors. Combining with the in-situ test data of the anchor rod reinforcement engineering, the network is trained and the errors are analyzed. Thus it verifies the applicability and feasibility of the method. Extended calculations are conducted by using the well-trained intelligent forecast model. Through application of orthogonal table test theory, 25 groups of tests are designed to analyze the sensitivity of influencing factors on the anchorage force of anchor rods in the soil. The results show that: the sensitivity of influencing factors on the anchorage force of soil anchor rods, in a descending order, is the length of anchoring segment, strength of the grouting body, anchor rod diameter, bore diameter, inclination angle of anchor rod. The results can provide reference for the practical application of the same reinforcement engineering.
