摘　　要：介绍基础相对刚度对螺栓规格选择计算的影响。说明单个螺栓(作用在翻转中心)受倾翻载荷时的最小螺栓预紧力确定过程,为精确确定螺栓预紧力,引入基础相对刚度,以得到优化解。The paper describes the influence of relative foundation stiffness on the calculation to choose proper bolt dimensions, and how to determine the minimum pretightening torque for a bolt( acting on the tilting center) under tilting load. The relative foundation stiffness is taken into consideration to determine precise pretightening torque in order to get an optimized result.

关 键 词：螺栓预紧力 倾翻载荷 基础相对刚度 螺栓设计
