柱式墩台盖梁的加宽设计

Widening Design of Bent Cap of Cylinder Pier Platform

改扩建工程中桥梁设计的重点是其下部加宽改建方案。一个理论上合理、工程上可行、造价较低的设计方案是极其重要的。本文主要介绍沈大高速公路改扩建工程中柱式墩台盖梁的加宽设计方案,并介绍采用平面杆系程序计算盖梁的方法。

In reconstruction and extension engineerings,the important point of bridge design is widening and reconstructing its bottom.The design schemes,which is rational in terms of theory,feasible in project,costs less,are extremely important.The paper chiefly introduces the widening design of bent cap of cylinder pier platform in reconstruction and extension engineerings of Shen-Da Freeway,and the methods for calculation of bent cap in plane rod-system procedures yet,which provides some references to widening of caps in the future.
