一、前言在火力发电厂土建结构设计技术规定中规定了当汽轮发电机基础建造在岩质土地的地基上时,应铺一层人工砂质弹性垫层(以后简称砂垫层),其厚度不少于200~300毫米,并采取适当的措施,以防止砂垫层从基座基础段中涌出。由于汽轮发电机系火力发电厂的心脏,基础结构此较重要,既要满足支承设备机械的强度要求,又要
I. Preface It is stipulated in the technical regulations of civil structure design of thermal power plant that when the foundation of the steam turbine generator is to be built on the ground of rocky land, an artificial sand elastic cushion layer (hereinafter referred to as sand cushion layer) The thickness of not less than 200 ~ 300 mm, and take appropriate measures to prevent the sand cushion from the base of the base section of the gushing. As the heart of steam turbine power plant, the infrastructure is more important, it is necessary to meet the mechanical strength of support equipment requirements, but also
