Abstract
For the purpose of some help toward the estimation method, authors developted back analysis scheme using nonlinear programming in heat conduction analysis based on the finite element method.
This paper demonstrates that the adotability of the back analysis method on the estimation of thermal characteristics of freezing ground is studied, and that the possibility of the back analysis method in the feedback system of field measurement results to design and temparature control in construction site using the soil freezing method is discussed.
