摘　　要：某高速公路特大桥2^(#)主墩位于深水中,为进行承台施工,首先进行了围堰方案比选。选择锁扣钢管桩围堰方案后,再对锁扣钢管桩围堰进行专门设计,并建立模型对其进行验算,最终得以成功实施。该桥2^(#)主墩承台实施表明,该方案切实可行,成本节约35.84%,工期节约15.17%。The 2^(#)main pier of a super large bridge on a certain expressway is located in deep water.In order to carry out pier construction,a comparison of cofferdam schemes was first conducted.After selecting the lock buckle steel pipe pile cofferdam scheme,a specialized design was carried out for the lock buckle steel pipe pile cofferdam,and a model was established to verify it,ultimately achieving successful implementation.The implementation of the 2^(#)main pier cap of the bridge shows that the plan is practical and feasible,with a cost savings of 35.84%and a construction period savings of 15.17%.
