Abstract：By using numerical analysis，a series of parametric studies for the maximum wall deflection induced by excavation in clay are performed. Based on the results of parametric studies，a simplified evaluation method for maximum wall deflection is proposed using multiple regressions. The proposed method is verified through four case histories. Based on the comparison between predicted maximum wall deflections and those from field observation，the predicted maximum wall deflections are generally within 0.85–1.15 times of observed deflections. Therefore，the proposed method can be used for preliminary prediction and design，and also done for checking the final results of design.
