贵州省阿志河大桥支座损伤研究

Study on Damage of Bearing Azhihe Bridge in Guizhou Province

根据JTG D60-2004《公路桥涵设计通用规范》、GB/T 17955-2009《桥梁球型支座》和JTG D62-2004《公路钢筋混凝土及预应力混凝土桥涵设计规范》的要求,对阿志河大桥球形支座在容许荷载作用下支座损伤进行了计算,分析了球形支座产生损伤的原因。研究表明,水平位移量超出了设计的水平位移量是支座损伤的主要原因。

According to the standard ＂Highway bridge and culvert design general specification （JTG D60 - 2004） ＂, ＂Bridge ball type bearing （GB/T17955 -2009）＂ and ＂ Code for design of highway reinforced and prestressed concrete bridges and culverts（ JTG D62 -2004 ）＂ The spherical bearings in the allowable loads bearing damage are calculated, analyzed the damage causes of spherical bearing. Research shows that, the horizontal displacement beyond the horizontal displacement of design is the main reason for bearing damage.
