The main span steelwork was fabricated at shekou in mainland china mainland and assembled on site into units of 8 . 7 metres long , the deck slabs being cast on each unit before erection 橋面主架由鋼制件組合而成,在中國內(nèi)地蛇口制造及于工地裝嵌成長(zhǎng)8 . 7米的組件,并于吊放前,在每塊組件上鑄造橋面平板。

Because it is simple to make manufacture slab with slightly curved bottom , and is economical to use steel , and is relatively great in aspect of load bearing potential capacity , the slab often has been used as braced arch and rigid - frame arch bridges " deck slab in 1970s and 1980s 由于微彎板具有制作簡(jiǎn)單、用鋼量省、承載潛力較大的優(yōu)點(diǎn),因而上世紀(jì)七、八十年代,在剛架拱橋、桁架拱橋中常用作橋面板。
