桥墩台改革在毛主席的革命路线指引下,以阶级斗争为纲,坚持党的基本路线,发动群众大力开展科研工作,大搞内外三结合,取得了较大发展。小截面墩台、空心墩、柔性墩等已开始在许多线路上试用,取得了良好的效果。在改革桥墩台方面,有关单位曾进行不同途径的研究,如外力大小、抗裂性等容许值。设计理论及改变结构受力条件等,都获得了不同的改进。其中改变结构受力条件,是使桥墩台达到轻型化的有效革新措施。目前桥台设计基本上采用重力式,用自身的重量来平衡侧向土压力,因而使桥台设计得笨重,圬工量大。我 Under the guidance of Chairman Mao’s revolutionary line, the reform of the bridge piers and units took the class struggle as the key link, adhered to the party’s basic line, mobilized the masses to carry out scientific research vigorously, and vigorously engaged in the integration of both inside and outside China and achieved greater development. Small sections pier, hollow pier, flexible pier, etc. have begun trial in many lines, and achieved good results. In respect of the reform of piers and abutments, the relevant units conducted different ways of research, such as allowable values ​​of external force and crack resistance. Design theory and change the structure of the force conditions, have received different improvements. Among them, changing the stress conditions of the structure is an effective innovation measure to make the piers and abutments lighter. At present, the abutment design basically adopts the gravity type, with its own weight to balance the lateral earth pressure, thus making the abutment design bulky and heavy labor. I
