摘要
利用数值分析,研究影响黏土层中基坑挡土墙最大变形量的参数,根据参数研究的结果,利用复回归分析,给出挡土墙最大变形量的简易评估法。然后利用简易评估法,预测4个台北基坑案例的连续墙最大变形量,并与现场监测结果进行比较。结果显示:预测的最大变形量在0.85～1.15倍监测值范围内。因此,本文给出的简易评估法,可为初步预测、设计及最后检核设计成果提供参考。
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.
