前言笔者在“电力建设”1981年第2期发表的《计算汽轮发电机基础纵向变形的地基刚度法》(以下简称“地基刚度法”)一文中,叙述了在粘土类土壤上的汽轮发电机基础纵向变形的分析原则与方法。本文则根据该文所提出的方法,对一般条件下的200兆瓦汽轮发电机基础底板纵向变形加以分析,并对基础底板挠度有影响的各个因素也加以评述,希望能对汽 Foreword In the article “Foundation stiffness method for calculating the longitudinal deformation of turbine generator foundation” (hereinafter referred to as “foundation stiffness method”) published in “Power Construction” No. 2 of 1981, the author described steam turbines on clay soils. Principles and Methods for Analysis of Longitudinal Deformation of Generator Foundations . Based on the method proposed in this paper, the longitudinal deformation of the base plate of a 200 MW turbine generator under normal conditions is analyzed, and various factors that affect the deflection of the foundation plate are also reviewed. It is hoped that
