以南京地铁三号线卡子门站为工程背景,运用有限差分软件FLAC3 D对基坑开挖进行数值模拟。模拟了桩体水平位移和钢支撑轴力在基坑开挖过程中的变化规律,并将模拟结果与现场实测结果进行了对比,分析了模拟结果与实测结果的差异以及产生差异的原因。结果可为数值模拟技术在基坑开挖中的应用提供参考。
以南京地鐵三號線卡子門站為工程揹景,運用有限差分軟件FLAC3 D對基坑開挖進行數值模擬。模擬瞭樁體水平位移和鋼支撐軸力在基坑開挖過程中的變化規律,併將模擬結果與現場實測結果進行瞭對比,分析瞭模擬結果與實測結果的差異以及產生差異的原因。結果可為數值模擬技術在基坑開挖中的應用提供參攷。

The finite difference software FLAC 3 D was employed to simulate excavation of foundation pit during sub-way excavation based on the third line of Nanjing subway project in this paper .The change regulation of the pile horizon-tal displacement and the steel shotcrete axial force were simulated .The results were compared with the measured in the construction field .The differences between the simulated and measured results and the reason were also analyzed .The conclusions can provide some references for the similar research in subway excavation .
