本研究將彙整王建智等人(2018)已完成高雄近港灣地區砂質土壤使用不同拌合水及膠結材料進行地盤改良,所獲得之抗壓強度和超音波速試驗結果,應用雙曲線函數 (hyperbolic function) 進行非線性多變數的迴歸分析,以建立抗壓強度和超音波速預測模式的研擬。試驗結果與分析值的比較顯示,抗壓強度試驗整體平均絕對誤差百分比MAPE值為9.48%;超音波速試驗MAPE值為0.76%。 顯示其預測分析模式在抗壓強度和超音波速等都有不錯之分析結果。並分別探討抗壓強度和超音波速評估分析模式關係方程式,為日後工程實務添加水泥改良土配比設計之參考。
In this study, Wang Jianzhi et al. (2018) have completed the construction of sandy soil in Kaohsiung near the harbor area using different mixing water and cement materials for site improvement. The obtained compressive strength and ultrasonic wave speed test results are applied by hyperbolic function function) Regression analysis of non-linear multi-variables to establish the prediction model of compressive strength and ultrasonic velocity. The comparison between the test results and the analysis values shows that the overall average absolute error percentage MAPE value of the compressive strength test is 9.48%; the MAPE value of the ultrasonic velocity test is 0.76%. It shows that its predictive analysis mode has good analysis results in compressive strength and ultrasonic speed. It also discusses the relationship between the compressive strength and ultrasonic wave velocity analysis model for reference for future engineering practice of adding cement to improve soil mix design.
