| Abstract: | Puba Arming River Superlarge Bridge pre-stressed concrete continuously beam carries on concrete construction by ＂87＂ type military beam as the support, which has achieved great success. And it has set the biggest span record of constructing the cross river bridge with the beam type support in the present Sichuan Province and even the whole nation. This technique result will promote the concrete cast-in-place beam type support span to a new phase. |
