一、概况 本试验包含支座转动性能、摩擦系数测定及静压等三项。所有试验均在室内用试验支座进行。同时作了聚四氟乙烯板的蠕变试验,取得了长期测定资料。 (一) 目的: 为广罗线箱板河1号铰接梁桥采用盆式橡胶支座设计及24米、32米预应力钢筋混凝土梁桥普遍应用盆式橡胶支座提供设计依据:
First, an overview This test includes bearing rotation, friction coefficient determination and static pressure of three. All tests are carried out indoors with test supports. Teflon plate also made a creep test, obtained long-term determination of data. (A) Objective: To provide the design basis for the application of basin rubber bearings for the design of the rubber hinge of the Guangluo Boxanhe No.1 articulated beam bridge and the 24m and 32m prestressed reinforced concrete girder bridges,
