| 摘 要： | 海洋平台的隔水套管群桩与土共同作用研究是一个很复杂的课题，目前国内外研究资料甚少，因此在平台导管架设计中，一般不考虑隔水套管群桩承受水平力作用，这与实际不相符合。本文结合工程课题，在调查研究和模型试验的基础上，对隔水套管群桩在水平力作用下的工作性状与破坏机理、群桩的水平力及其主要影响因素、单桩与群桩情况下应力应变关系等方面进行较深入的研究；并提出砂土地基隔水套管群桩效应经验公式，弥补了现行计算方法的缺陷和不足。研究成果可供工程设计参考使用。

| Abstract: | The study of interaction between the waterproof casing pile groups of oil platform and soil is a complicated problem, and there are few domestic and foreign materils for this at present. Therefore, in the design of the waterproof casing pile groups of oil platform, the lateral loads are always ignored. It is not agreeable with the facts. Combining with engineering projects, basing on investigation study and model tests, this paper has a thorough study about working behaviour and failure mechanism of outside waterproof casing pipes subjected to lateral loads, lateral bearing capacity of pipe groups and the primary influencing factor and relation between stress and strain of single pile or pile groups, and so on, Then a new corresponding experienced method of effect of pipe groups in sandy soil is presened, which makes up for the shortcomings of present methods and might be served as worth while reference to technicians and engineers. |
