通过构建的二维Plaxis储罐基础沉降模型,对阿布扎比原油管线项目位于沙漠地区的两座容积16×104m3的浮顶钢结构原油储罐基础的沉降进行模拟计算,得出罐底部沉降曲线,制定了采用预压法和强夯法相结合的罐基础施工方案,并通过现场试夯确定强夯参数。对施工程序的详细介绍和对施工过程中遇到的问题、改进方法、注意事项进行的总结,对类似工程施工有一定的参考价值。
Based on the constructed two-dimensional Plaxis tank foundation subsidence model, the settlement of two 16 × 104m3 floating steel structure crude oil storage tanks located in the desert of Abu Dhabi is simulated and the settlement curve at the bottom of the tank is obtained , Developed a prefabricated and dynamic consolidation method of tank foundation construction program, and through the field test to determine the dynamic compaction parameters. The detailed introduction of the construction procedure and the problems encountered in the construction process, the improvement methods and the summary of the precautions are of certain reference value to the similar construction.
