| 摘 要： | 文章以某绕城高速公路上跨分离式立交桥为工程背景,采用空间有限元分析法,对中承式连续梁拱组合桥进行施工阶段及运营阶段静力计算,分析钢管混凝土拱肋与预应力混凝土连续梁及吊杆内力、应力及位移随工序进程的变化规律。计算结果表明,该梁拱组合桥型能够充分利用各自构件的受力特性形成互补,同时拱梁的组合呈现美观的造型又兼具较好的技术经济指标。

| Abstract: | With the separate crossing overpass in a around-city expressway as engineering background,this article by using the spatial finite element analysis conducted the static calculation of half-through continuous beam-arch combination bridge during the construction phase and operation phase,analyzed the variation rules of concrete filled arch steel tube rib and prestressed concrete continuous beam as well as boom internal-force,stress and displacement with the processes.The calculation re-sults showed that the this beam-arch combination bridge can take full advantage of the force character-istics of their respective components to become complementary,meanwhile the beam-arch combination presents the beautiful shape and has good technical and economic indicators. |
