In the third engineering case , the author separately adopted duncan - chang model and linear elastic model . compared their results with the measured results , the author found that the duncan - chang model is more suitable to evaluate the settlement of soft ground 本文第三個實例分別采用了duncan - chang非線性模型和線彈性模型計算,將其計算結(jié)果與實測資料進行比較,結(jié)果證明用非線性模型比較符合工程實際。
