摘要
介绍了一种预应力钢支撑新型保载活络头结构,并通过现场试验的方式,与传统工艺钢支撑进行对比,对其保载效果进行分析。试验结果表明:新型保载活络头结构可有效降低预应力损失,围护墙水平位移量显著减小,有效保护了周边环境。
This paper introduces a new type of load retaining flexible head structure of prestressed steel support,and analyzes its load retaining effect by comparing it with traditional process steel support through field test.The test results show that the new load retaining flexible head structure can effectively reduce the prestress loss,significantly reduce the horizontal displacement of the retaining wall,and effectively protect the surrounding environment.
