摘　　要：针对梁底需要设置调坡楔形垫块且传统支座存在偏压和脱空弊端的问题,设计了一种具有自调坡功能的新型盆式支座,该支座可以实现0~0.08rad范围内任意方向的无级调坡功能。通过有限元软件对其力学性能进行了详细地计算分析,重点研究了不同调坡角度、接触类型以及地震水平荷载作用对支座性能的影响,并对支座进行了理论上的校核。研究结果表明,支座各部件刚度、强度均满足设计要求,且具有较高的安全系数。In view of the disadvantages of wedge pad for slope adjustment at the bottom of the beam and the bias and void of the traditional support,a new type of pot bearing with self-slope adjustment function is designed and proposed,which can realize the stepless slope adjustment function in any direction in the range of O~O.08 rad.The finite element software is used to calculate and analyze the mechanical properties of the bearing in detail,and the influence of different slope adjustment angles,contact types and seismic horizontal loads on the performance of the bearing is studied and analyzed,and the theoretical check of the bearing is carried out.The calculation results show that the stiffness and strength of each component of the bearing meet the design requirements and have a high safety factor.
