崇启长江公路大桥主桥为102+4×185+102=944m六跨钢连续梁桥,施工采用大节段整体滚装上船、水上运输、吊装架设的方案。大节段长度有55.6、146.8、185m3种,单件运输最大重量约2 566t。此类超长、超重结构的滚装上船及运输在中国属于首次,该文详细介绍了185m大节段滚装上船和水上运输的思路,并对滚装上船过程的体系转换、水上运输的支架方案进行了较为详细的介绍。
The main bridge of Chongqi Changjiang River Highway Bridge is a bridge with 102 + 4 × 185 + 102 = 944m, which is a six-span steel continuous girder bridge. The construction adopts the scheme of whole ro-ro on board, water transportation and hoisting erection. Large section length 55.6,146.8,185 m3 kinds of single-piece transport maximum weight of about 2 566t. This kind of super-long and overweight ro-ro embarkation and transport is the first time in China. This paper introduces the concept of 185m large-scale ro-ro and water transport in detail, and transforms the system of ro-ro onboard Transportation of the stent program carried out a more detailed introduction.
