将用作临时支护的排桩与桥梁永久构件的桥台结合起来，不仅能使结构受力合理，也节约了临时设施。本文对排桩基于水平土拱效应的合理间距、逆作法施工过程中排桩作为单支点支护桩的合理入土深度、桩身强度及作为永久桩基的最小桩长做了系统分析。
將用作臨時支護的排樁與橋樑永久構件的橋檯結閤起來，不僅能使結構受力閤理，也節約瞭臨時設施。本文對排樁基于水平土拱效應的閤理間距、逆作法施工過程中排樁作為單支點支護樁的閤理入土深度、樁身彊度及作為永久樁基的最小樁長做瞭繫統分析。

Combined a permanent abutment with temporary support pile, the bridge not only can make the structure more reasonable, also can save temporary facilities. The paper takes a system analysis for the reasonable spacing of pile foundation in horizontal soil arching effect, reasonable depth in the earth, pile strength and the minimum pile length of permanent pile foundation of rowed pile which is severed as support pile in top-down method construction.
