梁格法在小半径PC连续弯梁桥中的应用

介绍了小半径预应力连续弯箱粱桥的受力特点,以及梁格法的基本原理。以昆山某立交中的预应力混凝土连续弯梁桥为例,重点介绍了梁格截面刚度等效方法、一般原则,并提出了设计该类桥应该注意的问题和相应的措施。

Application of Grillage Method in Small-radius Prestressed Concrete Continuous Curved Bridge

This paper introduces the stress characteristic of small-radius prestressed continuous curved bridge and the basic principle of grillage method.Taking a prestressed concrete continuous curved bridge of a grade separation in Kunshan as an example,the article stresses introduction on the grillage sectional rigidity equivalent method and its common rules,and puts forward the relative measures and the problems for attention in the design of this bridge.
