| 摘 要： | 根据极限平衡和极限分析方法,建立了软黏土地基土体上海底管道的极限承载力计算公式。当地基处于极限状态时,基础作用于地基的全部荷载应该等于该地基土体的承载能力,根据这一关系式可以推导出海底管道沉降量的计算公式。通过对试验结果的分析,证实所采用的计算方法是可行的。

| Abstract: | Based on the techniques of limit equilibrium and limit analysis, the formulae are given to calculate the ultimate bearing capacity of offshore pipeline in soft clay. In the ultimate state, the ultimate bearing capacity should be equal to the loads acted on the foundation. Thus the solutions to pipeline settlement can be deduced. The suitability of proposed method is verified by model test. |
