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。
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.
