采用单箱单室梁截面形式,按照任务书要求用Midas Civil软件进行设计。本论文将具体介绍35m+55m+35m三跨连续刚构桥设计的过程,包括了连续刚构桥的尺寸拟定,单元划分,施工方法,内力

摘要:供道路、铁路、渠道、行人、管线等跨越海湾、河流、琥珀、低地、山谷等地型或其他交通线路时采用的建筑结构称为桥或者桥梁。在21世纪的今天,桥梁已经变成我们身边普遍且不可缺少的一部分,生活中我们随处可见形形色色的桥梁。连续刚构桥是墩梁固结的连续梁桥。连续梁桥是我们经常见到的一种桥梁的结构,预应力混凝土连续梁桥是它主要的结构形式,这样的结构形式具有变形量小、结构刚度好、抗震力强、养护方便等等优势。本次设计采用单箱单室梁截面形式,按照任务书要求用Midas Civil软件进行设计。本论文将具体介绍35m+55m+35m三跨连续刚构桥设计的过程,包括了连续刚构桥的尺寸拟定,单元划分,施工方法,内力计算,承载能力验算等等,从而确认桥梁设计符合计划书的要求。68756

Design of 35m + 55m + 35m Three - span Continuous Rigid Frame Bridge

Abstract:For buildings, bridges, roads, tunnels, pipelines, pedestrians, etc. The buildings used across rivers, bays, amber, valleys, lowlands or other traffic lines are called bridges or bridges. In the 21st century, the bridge has become a common and indispensable part of our lives, we can see everywhere in all kinds of bridges. The continuous rigid frame bridge is a continuous girder bridge. Continuous beam bridge is a commonly used bridge structure, prestressed concrete continuous beam bridge is its main form of structure, it has a small deformation, less expansion joints, structural rigidity, easy maintenance, seismic and other advantages. This design uses a single-box single-chamber beam cross-section, in accordance with the requirements of the mission book with Midas Civil software design. This paper will introduce the design of 35m + 55m + 35m three-span continuous rigid frame bridge, including the size of the continuous rigid frame bridge, unit pision, construction method, internal force calculation, load capacity checking, etc., to confirm the bridge design the requirements of the plan.

Keywords:Continuous rigid frame bridge; structural design; Midas Civil; cantilever construction method
