成都学院学士学位论文（设计） 1×30m预应力混凝土T型简支梁桥设计 专 业：土木工程（本） 学 号： 学 生： 指导老师： 摘要：预应力钢筋混凝土T型简支梁桥设计计算 随着经济的发展，交通已经成为社会的经济命脉，交通的不畅会制约着经济的发展,而桥梁又是交通设施中不可缺少的一部分，它的安全性对于我们来说是至关重要的，所以就需要对桥梁进行各方面的计算，来保证它能正常的工作。 本设计为预应力混凝土T型简支梁桥，桥梁总长30m，桥面净空：净—8+2×1.5m,，通过方案比选的方法确定桥梁的桥型，设计的主要内容包括：上部结构的内力，配筋计算，再进行强度，应力及变形计算最后在进行下部结构的计算。通过本次桥梁设计，使自己对桥梁的计算有了进一步的认识，我相信这对以后都是很有帮助的。 关键词：混凝土，T型简支梁，上部结构，预应力 1 x 30m prestressed concrete T beam bridge design Specialty: Civil Engineering Student Number: 201010211203 Student: Li Jianbing Supervisor: Yuan Ao Abstract: Reinforced Concrete Beams Pre-stressed T-shaped Beam Bridge Design Calculations With the development of economy, the traffic has become the lifeblood of social economy, Its smooth will restrict social development of economy. However, the bridge is an indispensable part of the traffic facilities, its safety is very important for us. So we need to calculate all aspects of the bridge, to ensure that it can work normally. This design for prestressed concrete T beam bridge, the bridge length of 30 m, the deck is clear: net - 8 + 2 x 1.5 m, and determine the bridge bridge by using the method of scheme comparison, design main content includes: the upper structure of the internal force and reinforcement calculation, for strength, stress and deformation calculation in the bottom of the structure of the calculation. It makes me have the further understanding of the calculation of Bridges through the design of the bridge. From my perspective, this design has a great influence on my future job.
