| 摘 要： | 通过对钢筋混凝土圆管涵进行结构优化，研发了一种新型的钢筋混凝土异型管涵结构，并对该异型管涵进行相应室内试验和有限元分析。室内静载试验采用千斤顶加压形式，分级加压直至钢筋混凝土破坏，得出钢筋混凝土异型管涵的极限承载能力、结构力学特性、裂缝发展趋势和结构破坏形式等。结合ANSYS有限元模型，深入了解异型管涵的受力性状和力学性能。通过对比圆管涵可知，钢筋混凝土异型管涵极限承载能力大大提高，结构受力也更为合理。

| Abstract: | According to the optimization of the reinforced concrete pipe culvert structure, it will be developed a new type of reinforced concrete heterotypic pipe culvert structure, And concrete heterotypic pipe culvert for the corresponding laboratory test and finite element analysis. Jack pressure form by static load test indoor, graded compression until the failure of the reinforced concrete, obtain the inspection of the reinforced concrete pipe culvert’s carrying capacity, mechanical properties and failure modes. The ultimate bearing capacity is greatly increased and the force structure is also more reasonable of reinforced concrete heterotypic pipe culvert by comparing the culvert pipe. |
