传统上,管道在热载荷作用下会产生向上屈曲的现象,称为管道隆起屈曲。为了分析这一现象,大多数以前的研究都将管道建模为一个长而重的梁,搁在刚性的海床上。然而,海床可能非常柔软且不平坦;因此,管道可能在热压缩力下穿透到海床中并改变其屈曲模式。研究了海床阻力对支柱缺陷下管道上拔屈曲的影响。结果表明,海底阻力对海底管道的屈曲现象有显著影响。
Conventionally a pipeline resting on a prop tends to buckle upward under thermal loads, which is called upheaval pipeline buckling. To analyze the phenomenon, most previous studies have modeled the pipeline as a long heavy beam resting on a rigid seabed. However, the seabed may be very soft and uneven; consequently, the pipeline may penetrate into the seabed under thermal compressive forces and change its buckling mode. This study is concerned with the effect of seabed resistance on upheaval buckling of pipelines with prop imperfection. We find that the seabed resistance exerts a remarkable influence on the phenomenon of upheaval pipeline buckling.
