整体式盖板在U型桥台台后沉陷中的应用研究

On application of integral cover board in back-stage settlement of U-shaped abutment and its research

通过分析台后沉陷的原因,研究出整体式盖板在解决U型桥台台后填土沉陷问题的技术,实践证明该技术彻底解决了U型桥台因台腔填土沉陷导致侧墙竖向开裂的问题,值得在实际工程中广泛应用和推广。

According to the analysis of the reasons of the back-stage settlement, the paper researches the technique of the integral cover board in solving the back-stage filled soil settlement of the U-shaped abutment, proves the technique can completely deal with the vertical cracks on the side wall of the U-shaped bridge abutment caused by the settlement of the soil in station cavity, so it can be worthy being applied extensively in projects.
