文章结合某拱桥止推墩基础施工实例，阐述了采用“排桩＋冠梁＋内撑”复合支护模式的深基坑桥梁基础施工方案，并利用有限元数值模型，计算分析了“排桩＋冠梁＋内撑”复合支护结构的受力状况及基坑稳定性。结果表明，该复合支护模式是有效、可行的。

Taking construction of an arch thrust pier base as an example,the article discussed a construction plan for deep excavation bridge base in composite supporting mode as ＂row pile ＋ top beam ＋ internal bracing＂ and using finite element value model,it calculated the stress and excavation stability for such a structure.It is proved that this composite supporting mode is valid and feasible.
