摘要
苏虞张一级公路跨沪宁高速公路跨线桥为主跨65m预应力混凝土连续箱梁,主桥采用平面刚构转体施工技术,大大减少了对高速公路的运营影响。对转体施工中的上、下承台、磨心、转体、合拢等进行了介绍,并提出建议供参考。
The main span of flyover of Huning expressway of Suyuzhang first - class highway is 65m prestressed concrete continuous box beam. The main bridge uses rotary construction technique of rigid framework of plane which greatly reduces the operational influence on the expressway. The upper and lower caps, the grind centre, rotation, shut and so on in rotary construction are introduced and suggestions are proposed for reference.
