style="text-indent:25px">鋼板箱形梁與傳統(tǒng)混凝土箱梁橋相比,波形鋼腹板組合箱梁橋由于上部結(jié)構(gòu)自重減輕,但剛度幾乎沒有減少,故而其自振頻率略有增大,但地震作用下各橋墩的彎矩和軸力均有較大幅度的減小,結(jié)構(gòu)抗震能力明顯提高;表明波形鋼腹板組合箱梁的抗震性能要明顯優(yōu)于傳統(tǒng)混凝土箱梁,是值得在我國西部高烈度山區(qū)推廣的一種較合理的橋型方案。箱型梁由于用途的特殊性，箱型梁作用很大，所以在生產(chǎn)加工時(shí)必須嚴(yán)格保證質(zhì)量。箱型梁生產(chǎn)加工廠家在新源物資交易市場(chǎng)比較多，具體可以實(shí)際考察。箱梁在**場(chǎng)地預(yù)制的箱梁結(jié)合架橋機(jī)可在下部工程完成后進(jìn)行架設(shè)。</p><div
