摘　　要：公路桥梁经常需要跨越河道,这对于此类工程的水下灌注桩施工提高了施工难度,本文依托滨玉公路改造工程背景,介绍了公路桥梁水下混凝土灌注桩的施工技术,对可能出现的事故原因进行分析,并提出了相应对策。为同类工程施工提供借鉴。Highway bridges often need to cross the river,which improves the construction difficulty of underwater cast-in-place piles for such projects.Based on the Binyu Highway Reconstruction Project,this paper introduces the construction technology of underwater concrete cast-in-place piles for highway bridges,analyzes the possible causes of accidents,and puts forward corresponding countermeasures to provide reference for the construction of similar projects.

关 键 词：水下灌注桩 事故 混凝土灌注 公路桩基
