style="text-indent:25px">目前，常規(guī)的貝雷鋼橋安裝技術(shù)主要采用懸推法，即采取在正橋前端設(shè)置導(dǎo)梁先搭到對(duì)岸橋墩后再逐步牽拉正橋到位。在懸推過程中，若穩(wěn)定力矩小于傾覆力矩，還需在貝雷鋼橋桁架后方配重。相反地，常規(guī)的貝雷鋼橋拆除技術(shù)主要采用懸拉法，即按照與懸推法相反的順序進(jìn)行逐步拆除。然而，無論是采用懸推法安裝還是采用懸拉法拆除貝雷鋼橋，因貝雷鋼橋的自重較大，存在發(fā)生傾覆的潛在風(fēng)險(xiǎn)，因此需要對(duì)現(xiàn)有技術(shù)進(jìn)一步改進(jìn)以提高其抗傾覆能力或降低傾覆事故的風(fēng)險(xiǎn)等級(jí)。此外，如果貝雷鋼橋用于船閘改擴(kuò)建工程，考慮到洪水沖刷的風(fēng)險(xiǎn)因素，在防洪度汛期間對(duì)貝雷橋也需采取一定的加固措施。</p><p
