一、概述伊拉克摩苏尔五桥,跨底格里斯河,主桥东端的引桥,为六车道的匝道桥。这个在主桥东头处的六车道,通过各过渡段,最后以分散的四个匝道桥与路基衔接,其简要的平面布置如图1所示,其各匝道位置及宽度技术指标如表1所示。全匝道桥共有716片梁,最长27m,最短12.3m,其中除过渡1、2、3、4的第1跨为等长梁外,其余长度均不同。这样的716片梁,组成了一座立体的弯、坡、斜匝道
I. Overview The five-bridge of Mosul in Iraq, crossing the Tigris River and the approach bridge at the east end of the main bridge is a six-lane ramp bridge. The six lanes at the east end of the main bridge pass through the transitional sections and finally connect the subgrade with four scattered ramp bridges. The brief layout of the six lanes is shown in Figure 1, and the technical specifications of each ramp position and width are shown in Table 1 As shown. Ramp bridge has a total of 716 beams, the longest 27m, the shortest 12.3m, of which in addition to the transition 1, 2, 3, 4 for the first span for the beam, the remaining length are different. This 716 beam, formed a three-dimensional bend, slope, ramp ramp
