Behavior prediction method in excavation excavation

摘要

The present invention relates to a method for predicting behavior during soil excavation, and more particularly, to a method for predicting behavior using fuzzy theory. The present invention has no non-uniformity in estimates and can quickly determine the ground microindex by performing accurate estimation suitable for the measured values in a short time. The object of the present invention is to provide a method for predicting the behavior during excavation, and to solve the problem, in the method for predicting the behavior during excavation, the initial design value is calculated when there is a difference between the measured behavior value and the original design value. Set the change δ that increases or decreases the ground material properties such as the earth pressure P, ground reaction coefficient Ke, ground adhesion force c, ground friction angle Ø, ground volume γ, and brace spring coefficient Ks on the membership function. s41) and the calculated behavior values when the change amount δ is plurally decreased (s48), and the ground physical properties when the calculated behavior values and the measured behavior values are roughly matched. And a brace to the spring coefficient Ks characterized in that (s51) to a hwakjeongchi.
