Title:
STEEL CYLINDER ANTI-OVERTURNING STABILITY PREDICTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/197880
Kind Code:
A1
Abstract:
Disclosed is a steel cylinder anti-overturning stability prediction method. Assuming that a steel cylinder topples towards a sea side at any rotating point, the pressure of a filler inside the steel cylinder, the external friction force, the internal friction force, and the vertical reaction and horizontal resistance of a foundation bed to the steel cylinder are calculated, an anti-overturning moment and an overturning moment under the condition that the steel cylinder topples towards the sea side are calculated, and the safety coefficient of toppling towards the sea side is obtained; then assuming that the steel cylinder rotates towards a land side under the same rotating point, the safety coefficient of toppling of the steel cylinder towards the land side is calculated, the two safety coefficients are compared, and the smaller one of the two safety coefficients is used as the safety coefficient under the rotating point; and then new rotating points are reselected, the safety coefficients corresponding to the new rotating points are calculated according to the steps above, and the minimum one of the safety coefficients in all the rotating points is used as the final safety coefficient under the working condition.
