| 摘 要： | 校验《铁路桥涵极限状态法设计暂行规范》(Q/CR 9300—2014)的适用性,以现行的铁路工程建设通用参考图《时速350 km客运专线铁路圆端形实体桥墩》(通桥(2009)4301—Ⅰ)为例,对墩身截面偏心、强度及稳定性等控制因素进行容许应力法与极限状态法对比分析。对比结果表明两种检算方法的安全储备是一致的,极限状态法规范所拟订的荷载分项系数也是合理、适用的。

| Abstract: | This allowable stress method and limit state method are employed to compare and analyze the eccentricity,strength and stability of pier cross-section based on Provisional Specification for Railway Bridge and Culvert Design with Limit State Method( Q / CR 9300—2014),and the current railway engineering construction common reference drawing Round-end Solid Pier for 350 km / h Passenger Dedicated Railway( 2009 4301—Ⅰ). The results show that the safety margin of the two methods is consistent and the loading partial factor estimated by limit state method is reasonable and applicable. |
