本研究的目的為探討軟弱粘土層中深開挖地表沉陷之主要影響區。本研究採用修正擬塑性模式的有限元素法深開挖分析程式,對三個監測紀錄良好的開挖案例進行分析,分析結果顯示在壁體位移及地表沉陷方面都可以獲得合理之預測。接著本研究進行一系列主要影響範圍之參數研究,研究結果顯示,主要影響區可以根據歐章煜和謝百鈎(2000)依據物理模型所得之方法決定。本研究亦利用參數研究的結果,建議主要影響區位置處之沉陷量以0.15倍的最大地表沉陷量估計,並且根據各假設案例求得地表最大沉陷量發生位置為0.33倍的主要影響區。最後本研究根據現地監測經驗及有限元素法參數研究之結果,建立一地表沉陷剖面預測法,並對五個實際開挖案例進行地表沉陷曲線之預測且與現地監測值做比較,由比較結果得知,可以獲得相當好之預測結果。
The purpose of this study is to confer the primary influence range of the ground surface settlement caused by deep excavation in clay. Three excavation cases with complete field observations are studied using the finite element method in conjunction with the modified pseudo-plasticity model. Analytic results show that the method can predict the wall deflection and ground surface settlement reasonably. Then, a series of parametric studies on the primary influence range using the finite element method is carried out. The results show the primary influence zone can be determined by Ou and Hsieh’s method based on the characteristics of failure modes. Then, this study proposes that the settlement of the location of the primary influence zone is 0.15 time maximum ground surface settlement and the location of maximum ground surface settlement is 0.33PIZ from the results of parametric studies. Finally, based on field observation’s experiences and the results of parametric studies, a method for predicting the ground surface settlement profile is proposed. The method is used to predict settlement curve for five excavation cases. Comparing the forecasted results with the field observations, the proposed method obtained a fairly reasonable prediction.
