The height and position of coil structures 300 and the height and position of mud level are consistent.At the height and position of mud level, especially
At the mud suddenly deep water of dehydration head decline, due to the circumferential direction that under the crunch of inside and outside head difference generation, casing is subject to
Pressure is maximum, so that casing is easy to generate failure (such as elastic instability) at this location, it is therefore desirable to strengthen to the position.
It is found that the mechanical model of Deep-water bored pile casing 100 is thin-walled rotator shell, and when elastic instability occurs, cylinder
The compression stress of wall is usually less than the proportional limit of material.According to ideal cylindrical shell small deflection theory, steel casing unstability is faced
