大型储油罐地基承载状态模拟及实例分析

摘要

通过FLAC2D软件对大型石化厂区大型储油罐地基承载状态进行了模拟，选取了各种土层参数和基础参数，将计算结果的地基沉降和实际监测数据作了对比分析，研究了在大型储油罐荷载下地基内部的应力变化和土体的屈服状态，并以广东某石油化工厂区为例，从附加应力响应、土体变形和周围土体变形进行数值分析，结合工程实测数据进行对比研究，得出了一些结论。%The paper simulates the large-scale oil tank storage foundation bearing status at some large petrochemical areas with FLAC2D software, selects the stratum and foundation parameter, undertakes the comparative analysis of the foundation settlement and factual monitoring data with the calculation results, researches the stress in the foundation and yielding status under the large-scale oil tank storage bearing, has the numeric anal-ysis of the additional stress response, soil deformation and surrounding soil deformation by taking some petrochemical factory in Guangdong as the example, has the comparison by combining with engineering data, and achieves some conclusions.
