摘要
介绍采用施加竖向预压力来主动闭合水平裂缝,通过增大砌体水平剪切面之间的水平摩擦力提高桥台的水平抗力,为石拱桥的圬工桥台增大水平抗力加固找出一种有效方法。
Vertical pre-compression method is adopted to seal horizontal cracks. By increasing the horizontal friction between masonry shear surfaces, the horizontal shear of the abutment is improved greatly. It＇s an effective way to enhance horizontal resistance.
