摘　　要：文中以阳西县城至溪头沿河道路大洲村段桥梁建设工程为例,阐述了工程强风化花岗岩地质条件,结合钢管桩沉桩施工难点,提出了应对钢管桩焊接防腐加工偏差、钢管桩起吊偏差、桩尖端断裂等难题的具体措施,以供参考。The article takes the bridge construction project of Dazhou village on the road from the Yangxi county town to Xitou along the river as an example,briefly explains the geological conditions of strongly weathered granite in the project,and combines the difficulties of steel pipe pile sinking construction to propose construction technology application measures to solve the welding and anti-corrosion processing deviation of steel pipe piles,lifting deviation of steel pipe piles,and pile tip fracture.The construction effect is analyzed to provide reference for relevant workers.
