作者认为对以往大量的小型梁式桥梁的桥台设计,一般注重了抵抗墙后填土的压力,而忽视了台前土抗力的作用等,往往设计断面很大,尤其基础埋得越较,墙身截面越大,这是不太合理的。本文考虑了台前土抗力作用,并把墙顶作为自由端看待,探讨了梁式桥台设计的新型计算方法,又附有算例,可供参考。
The author believes that the bridge abutment design of a large number of small beam bridges in the past generally focuses on the pressure of resisting the backfill of the wall but neglects the role of soil resistance in the front of the platform. The design cross section is often large, The larger the wall cross-section, this is not very reasonable. In this paper, the effect of soil resistance on the platform is considered, and the top of the wall is taken as a free end. A new calculation method of beam abutment design is discussed, with an example for reference.
