摘要
根据三山南桥现状及荷载等级提高要求,提出采用钢管桩加固方案。通过加固前后计算分析,知钢管桩可以有效地减少主梁正弯距,提高桥梁的承载力。加固后桥梁组成构件满足提载后的强度要求,钢管桩加固方法技术可行。
The strengthening scheme is proposed to brace the bridge by steel-pipe pile, according to the bridge current situation and load promoting requires. The load bearing capacity of the longitudinal girder can be improved efficiently, and its positive moment can be reduced sharply by this method. The member of this bridge can meet the strength requires after reinforcement, it is practicable in technique by steel-pipe pile supporting.
