超载下独柱墩横向抗倾覆计算研究

Calculation of Lateral anti-overturning of Single Pillar Pier Under Overload

近年来独柱墩倾覆事故让人触目惊心,桥梁倾覆问题被社会广泛关注。以福建宁德在建的一座独柱墩梁桥为依托,根据2015年《广东省高速公路独柱墩连续箱梁桥横向抗倾覆安全性评估验算指导意见》与2018年《公路钢筋混凝土及预应力混凝土桥涵设计规范》分别验算其横向倾覆稳性,探讨设计的验算指标,旨在为设计者提供有价值的参考意见。

In recent years, the overturning accident of single pillar pier is shocking, and the overturning problem of bridge has been widely concerned by the society. Taking fujian ningde of a single column pier girder bridge under construction as the backing, according to the 2015 "guangdong province highway single column pier continuous box girder bridge lateral rigidity safety assessment check guidelines " and 2018 "highway reinforced concrete and prestressed concrete bridge and culvert design specifications", respectively calculating the transverse overturning stability, to explore a more comprehensive design check target, It aims to provide valuable reference for designers.
