昆钢大型组合沉井问题数值模拟研究

Numerical simulation study of a large-scale compounding caisson in Kunming Iron and Steel Company

以昆明钢铁(集团)公司炼钢场区内旋流池分项工程的主要地下结构(大型组合沉井)为研究对象,对组合沉井下沉过程中的不同深度位置进行数值模拟分析,得出井壁的受力图、位移图和变形速度图;模拟结果基本与现场组合沉井实施情况吻合。

Taking the major underground structure （large compounding caisson） of steelmaking area swirl pool engineering in kunming Iron and Steel （Group） Company as a study object, the compounding caisson different sinking depth was analysed by numerical simulation. The stress pattern, displacement and deformation velocity map were obtained. The simulation results coincided basically with the scene compounding caisson.
