碎石环梁基础在大型储罐建设中的应用越来越广泛,其对地基沉降的影响尤为重要。本文结合工程实例,根据现场原位试验测试数据并结合经验值,确定并修正了土体模型参数,通过建立三维有限元模型,计算了研究区油罐地基的最终沉降量,并与现场监测数据进行对比,重点分析与比较了碎石环梁和混凝土环梁在大型储油罐强夯地基中的变形。研究结果表明,碎石环梁基础在调节罐周差异沉降方面具有明显的优势。
The application of gravel ring beam foundation in large tank construction is more and more widespread, and its influence on foundation settlement is particularly important. According to the engineering example, according to the on-site test data in situ and the experience value, the soil model parameters were determined and corrected. The final settlement of the foundation of the oil tank in the study area was calculated by establishing the three-dimensional finite element model and compared with the field monitoring data Compared and analyzed and compared the deformation of gravel ring beam and concrete ring beam in the dynamic compaction foundation of large oil storage tank. The results show that the gravel ring beam foundation has obvious advantages in adjusting differential settlement of cans.
