摘　　要：在快速路工程中,为车辆和行人通行设置的门洞设计至关重要,支架系统的选择和设计直接影响工程的安全性和稳定性。该文以沈阳市某快速路工程为背景,分析和比较“贝雷梁+盘扣支架”与“型钢+盘扣支架”2种支架形式。通过使用Midas Gen建立有限元模型,对2种支架形式进行模拟和分析。计算得出贝雷梁+盘扣支架最大组合应力为190 MPa,型钢+盘扣支架最大组合应力为203 MPa,且贝雷梁+盘扣支架在关键受力部位的应力分布较为均匀。综合评价2种施工方案的适用性,为类似工程提供参考。In expressway projects,the design of door openings for vehicles and pedestrians is crucial.The selection and design of support systems directly affect the safety and stability of the project.Based on a expressway project in Shenyang City,this paper analyzes and compares two support forms:Bailey beam+coil buckle support and section steel+coil buckle support.Two stent forms were simulated and analyzed by establishing a finite element model using Midas Gen.The calculation shows that the maximum combined stress of Bailey beam+disc buckle bracket is 190 MPa,and the maximum combined stress of section steel+disc buckle bracket is 203 MPa,and the stress distribution of Bailey beam+disc buckle bracket is relatively uniform at key stress positions.Comprehensively evaluating the applicability of the two construction plans can provide reference for similar projects.
