摘要:

随着储罐向大型化方向发展,基础沉降、结构变形等影响大型储罐运行的结构安全问题已成为设备管理和检验人员关注的重点,开展大型储罐基础沉降检测和结构完整性评价研究对保障大型储罐安全运行具有实际意义。基于储罐的基础沉降类型及其典型损伤形式研究,结合储罐在设计建造、定期检验等不同储罐服役阶段的特点,提出了储罐基础沉降检测要求,明确了不同类型沉降的检测和评价方法;针对罐壁不均匀沉降,开展分级评价方法研究,提出包含沉降差评价、偏离平面沉降幅度评价、局部非均匀平面沉降评价、应力分析评价的基础不均匀沉降4级评价方法,为技术人员开展储罐罐壁沉降安全评价工作提供了科学依据。

Abstract:

With the development of large-scale storage tanks,structural safety issues such as foundation settlement and structural deformation that affect the operation of large storage tanks have increasingly become the focus of equipment management and inspection personnel.Research on foundation settlement detection and structural integrity evaluation of large storage tanks is of practical significance for ensuring the safe operation.This article analyzes the types and typical damage forms of tank foundation settlement,and proposes requirements for tank foundation settlement detection based on the characteristics of different tank service stages such as design,construction,and regular inspection.It clarifies the detection and evaluation methods for different types of settlement,and focuses on the research of graded evaluation methods for uneven settlement around the tank.A 4-level evaluation method for basic uneven settlement,including settlement difference evaluation,deviation from the plane settlement amplitude evaluation,local non-uniform plane settlement evaluation,and stress analysis evaluation,is proposed to effectively support equipment management and inspection personnel in conducting structural suitability evaluation under tank foundation settlement conditions.

Key words: Storage tank, Foundation settlement, Failure mode, Quantitative evaluation
