黑部川大桥(Kurobegawa Bridge,见图1)位于日本富山县黑部市的北陆新干线上,跨河流部分为6跨连续波形钢腹板箱梁桥,长344m,跨径布置为(2×50+2×72+2×50)m,箱梁高3.3~4.8 m。中间3个桥墩支点处墩梁固结,其它桥墩支点处采用滑动橡胶支座支承。该桥是日本首座波形钢腹板铁路桥,由于铁路桥活载比公路桥大,因此对桥梁的疲劳耐久性进行了各种试验研究,结果发现在波形
The Kurobegawa Bridge (see Figure 1) is located on the Hokuriku Shinkansen in Kurobe, Toyama Prefecture, Japan. The cross-river section is a 6-span continuous corrugated web box girder bridge measuring 344 m in length with a span of (2 × 50 + 2 × 72 + 2 × 50) m, the box girder height 3.3 ~ 4.8 m. In the middle 3 bridge piers fulcrum pier beam consolidation, other pier fulcrum with sliding rubber bearing support. The bridge is Japan's first corrugated steel web railway bridge, railway bridge live load than the highway bridge, so fatigue durability of the bridge conducted a variety of experimental studies found that the waveform
