基于美标的火电厂水工构筑物地下结构设计研究

ELEMENTARY ANALYSIS ABOUT THE DESIGN OF HYDRAULIC UNDERGROUND STRUCTURE IN THERMAL POWER PLANT BASED ON AMERICAN STANDARDS

火电厂水工构筑物地下结构是电厂的重要组成部分,具有体量大、工作环境复杂、结构分析困难等特点。为了更好的基于美标进行其地下结构设计,研究美国主要结构设计规范中的设计方法和规定,包括荷载、荷载组合、侧土压力计算、混凝土耐久性等方面。通过研究,明确了美标水工地下构筑物的设计流程和方法,实现了运用STAAD.PRO进行全过程的美标结构设计。美标结构设计体系与国标差异较大,积极深入开展基于美标的水工构筑物结构设计研究工作,对于扩展海外市场,极具理论和现实意义。

Hydraulic structures are important components of a thermal power plants,wuth many particularities such as large volume,complex working environment and difficulty in analysis.In order to design a rational structure based on American standards,this paper studied the regulation in the major structural design specifications in the United States,such as loads,the loads combinations,the lateral earth pressure,durability of concrete etc.According to the research,this article nailed down the process and method of designing American-standard hydraulic underground structure,and realized whole-process American-standard structure design by using STAAD.PRO.The American standards are very different from the GB in the design system between,so there are some theoretical and practical significanc to study the design of hydraulic structure based on American standards,which is benifitefor developing overseas design market.
