本文扼要介绍我国若干座预应力混凝土连续梁桥的设计和施工。这几座大桥分别采用简支连续、悬臂拼装、悬臂浇注、分段顶推以及在移动支架上逐跨现浇等典型的连续梁施工方法。本文还就应用于上述桥梁结构计算的大型通用程序GQZJ-79中的若干计算原理作了简要介绍。 This article briefly introduces the design and construction of several prestressed concrete continuous beam bridges in our country. These bridges are used simple continuous support, cantilever assembly, cantilever casting, sub-push and in the mobile stent cross-cast and other typical continuous beam construction methods. This article also briefly introduces several calculation principles applied to the large general program GQZJ-79 for bridge structural calculation.
