埋地卧式容器外载荷分析

摘要

Buried horizontal vessel also sustains earth pressure compared to horizontal vessel which is on the ground.The distribution regularity of normal static pressure of buried horizontal vessel is complex under the effect of earth pressures,and for the design and calculation,no spe-cific standard and code to be based on till now.This relation between buried depth,vessel outside diameter and normal static pressure are discussed based on parametric-sensitivity analysis meth-od.The peak value of normal static pressure on buried horizontal vessel varies with the buried depth and vessel outside diameter.%埋地卧式容器与常规卧式容器相比，要额外承受土压力作用，其值对此类容器的稳定性校核至关重要。埋地卧式容器在土压力作用下的法向静压力分布规律较为复杂，对于其设计计算，目前也没有明确的标准规范可依。采用参数敏感性分析方法，探讨了埋地深度和容器外径与埋地卧式容器法向静压力的关系。模拟计算和分析表明，埋地卧式容器法向静压力最大点随着埋地深度及容器外径的变化而发生变化。
