| 摘 要： | 基于某国内预应力工程,首次对原型预应力盾构管片结构环衬砌进行摩阻损失测试。采用夹片-P锚结合的环锚技术,对预应力管片环施加预应力,以满足其承受内水压和外荷载的要求,较准确地获得了环形预应力盾构管片摩阻损失。同时初步确定摩阻系数,并对试验数据进行处理和分析。结果表明,测试结果与设计理论值比较吻合,可以满足实际试验要求。 |

| Abstract: | Taking some prestress engineering as example,it is the first time to test the friction loss of full-scale circumferential prestressed & precast concrete segment lining in China.The prestressed & precast concrete segment lining is prestressed by using the annular anchorage technique of anchor blade combining with P-anchor in order to withstand the internal water pressure and external load.It is the first time to achieve the friction loss of circumferential prestressed & precast concrete segment lining more a... |
