| 摘 要： | 对拱涵设计过程中土压力的计算、计算模型的选择进行了阐述,并着重分析了不同拱圈矢跨比对结构内力的影响,分析结果表明,矢跨比的选择与跨径、地基抗力系数等因素相关,随着跨径、地基抗力系数的增大,最优矢跨比减小。

| Abstract: | This thesis describes the earth pressure calculation and calculation model selection in the process of arch culvert design, analyzes the impacts of different arch rise-span ratios on structural internal force. Results show that ： rise-span ratio selection is relevant to span-diameter and foundation pressure against force coefficient etc. , with the increasing of span-diameter and foundation resistance force coefiticient, the optimum rise-span ratio will reduce. |
