基于三维数值模拟的钢渣堆载模式影响下工业厂房稳定性分析
Analysis of the Effect of Steel Slag Stacking Pattern on the Stability of Industrial Plants
专用钢结构工业厂房是工业生产中倾倒以及临时存储钢渣的关键构建筑物之一,然而其长期服役于复杂堆载环境下,易发生劣化。本文通过构建巴关河渣场主厂房的三维数值模型,系统分析了不同钢渣堆载模式对厂房结构稳定性的影响,重点关注地表变形特征、桩体侧移特征及临近柱沉降特征等关键指标。结果表明,堆载分布形式、距离及堆载大小是影响结构沉降与侧移的关键因素。随着堆载距离的增加,厂房结构的沉降量及侧移值逐渐减小,并当堆载距离超过特定值后,这些变化趋于稳定。此外,堆载水平的增加会导致沉降量和侧移量显著增加,尤其是在达到一定程度后,增长速率会显著提高。进而提出了钢渣堆载区域与承台边界之间的最小安全距离和最大堆载水平,以确保厂房结构的长期稳定性。本研究可为类似工业厂房的设计与风险预警提供理论依据,并有助于改进当前钢渣的处置策略。
Specialized steel-structure industrial workshops are among the key structures used for steel slag tipping and temporary storage in industrial production.However, long-term service under complex stockpiling loads makes them prone to performance deterioration.In this study, a three-dimensional numerical model of the main workshop at the Baguanhe slag yard is developed to systematically evaluate the effects of different steel-slag stockpiling modes on structural stability, with particular attention to critical indicators including ground-surface deformation, pile lateral displacement, and settlement of adjacent columns.The results indicate that the load distribution pattern, loading distance, and stockpiling magnitude are the dominant factors governing structural settlement and lateral movement.As the stockpiling distance increases, both settlement and lateral displacement of the workshop decrease progressively, and these variations tend to stabilize once the distance exceeds a threshold value.In addition, increasing stockpiling level leads to marked increases in settlement and lateral displacement, with a pronounced acceleration in the growth rate beyond a certain loading intensity.Based on these findings, a minimum safe clearance between the steel-slag stockpiling zone and the pile-cap boundary, together with a maximum allowable stockpiling level, is proposed to ensure the long-term stability of the workshop.This study provides a theoretical basis for the design and risk early warning of similar industrial workshops, and it may also facilitate improvements in current steel-slag disposal strategies.
