Backgrounded by the main bridge of Zhanhe River Bridge at Chengdonghe Road,Pingdingshan City,the software MIDAS/Civil is used to establish a 3-dimensional finite element calculation model for the double X-shape arch bridge and the effect of arch rib sloping angle changes on the dynamic performance of the type of the bridge is studied respectively for six design alternatives.
以平顶山市城东河路湛河桥主桥为工程背景,采用有限元软件MIDAS/Civil建立该桥的空间有限元计算模型,分6种设计方案研究了拱肋倾角变化对斜靠式拱桥动力性能的影响。
补充资料：包角踏脚
包角踏脚 明清家具术语。椅子的踏脚枨凸出脚面，截断面似倒置的直角梯形。两端出榫后“皮子”包住半根脚，故曰“包角踏脚”。
