［摘要］以某跨海鋼結構拱橋項目為例，對海邊建筑深基坑采用有限元軟件MIDAS GTS和理正深基坑支護結構設計軟件進行整體建模分析。結果表明：對于中心位置為近似圓形、周邊組合不規(guī)則多邊形的深基坑，可采用僅在圓形與不規(guī)則多邊形交界位置設置內支撐的支護形式，使中心區(qū)域形成封閉的近似圓形空間，從而取得良好的支護效果及經濟效益。

Abstract:Taking a cross-sea steel arch bridge project as an example, the finite element software MIDAS GTS and the Lizheng deep foundation pit supporting structure design software were used to perform overall modeling analysis for the deep foundation pit of a seaside building. The results show that: for deep foundation pits whose center is approximately circular and the periphery combined with irregular polygons, a support form that only sets internal supports at the junction of the circular and irregular polygons can be used to make the central area form a closed approximate circle space, so as to achieve good supporting effects and economic benefits.
Keywords:deep foundation pit; supporting structure; arch bridge; internal support
