摘　　要：文章基于有限元分析的计算方法,对基于结构—岩土共同作用的道路悬臂结构的半桥式路基进行了仿真计算分析,与传统的挖高填低路基结构进行了比较。在个案支持下,相同规模的挖高填低基础的有限元计算分析结果,其稳定性、可靠性、安全性均不及半桥式基础。在个案的工程设计方案对比阶段,虽然半桥式结构在土石方排出、预制件运输等过程存在一定的技术制约,但单纯从结构计算方面,半桥式结构的优势较为明显。文章认为,如果克服相关技术的制约,半桥式结构在未来山区道路施工过程中有推广价值。In this paper,based on the calculation method of finite element method,the half bridge subgrade of the cantilever structure of the road based on the structure rock soil interaction is simulated and analyzed,and compared with the traditional subgrade structure of digging high and filling low.With the support of individual cases,the finite element calculation and analysis results of the same scale of digging high and filling low foundations are not as stable,reliable and safe as half-bridge foundations.In the comparison phase of the engineering design plan of the individual case,although the half bridge structure has some technical constraints in the process of earthwork discharge and prefabricated parts transportation,the advantages of the half bridge structure are obvious only from the aspect of structural calculation.In this paper,if customer service technology constraints,half bridge structure in the future mountain road construction process has the promotion value.
