| 摘 要： | 根据极限平衡和极限分析方法,首先建立了软土地基土体上海底管线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线沉降量的计算公式.最后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,formulae are given to calculate the ultimate bearing capacity of submarine pipelines 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 could be deduced.The suitability of proposed methods is verified by model test. |

| Keywords: | submarine pipeline ultimate bearing capacity settlement slip line limit analysis model test |
