Abstract
Observational Procedure of the excavation work is mainly used for safe management. The prediction based on measurement data during construction is more reliable than the prediction at the design stage before construction. If the values are utilized more effectively, we will be able to execute the construction works rationally. So, Estimation of the design parameters and prediction in the behavior of the structure play the important roles in the observational procedure, and are demanded high reliability.
In this paper, the relationship between the error of measurement data and prediction results and the error in modeling of prediction are specified. And the reliability of the prediction are estimated.
