A Study on Feed Back System for the Geotechnical Parameter Estimation in Underground Construction

지하구조물 건설시 역해석에 의한 지반특성치 산정

This paper deals with a feedback system for the estimation of geotechnical parameters in underground construction works. The Ordinary Least Square (OLS) Optimization Method is utilized and combined with Finite Element Program so that optimum values of ground properties can be estimated. The preperties that can be estimated are Young's and Brown's failure criteria is proposed.
