制动墩【abutment pier】指为承受单向较大的水平推力，保证桥墩的稳定，因而尺寸较厚实；与梁桥重力式桥墩相比较，具有拱座等构造设施。
本文介绍了墩台承受水平力类型，理想情况温度力、制动力如何计算，非理想情况如何简化分析，以及设计中注意的问题。
The paper introduced type of level force of flexible pier base, how to calculate perfect temperature force, brake force, how to analyze non-perfect condition, and the noticed problems in the design.
研究目的：通过研究在制动力作用下墩顶刚度的提高程度，验证现行设计规范的合理性。
Research results: According to the measured data, the increased range of stiffness of bridge pier is less than 3%.
