[提要] 簡要介紹了桶形基礎(chǔ)在抗拔承載力方面的研究現(xiàn)狀，根據(jù)桶形基礎(chǔ)應(yīng)用地區(qū)的灘海地質(zhì)情況制備模型試驗(yàn)地基基礎(chǔ)。為了了解桶形基礎(chǔ)在這一地區(qū)的抗拔承載力情況，對不同桶深的桶形基礎(chǔ)進(jìn)行抗拔承載力試驗(yàn)，分析桶形基礎(chǔ)抗拔承載力的作用機(jī)理，同時(shí)，考慮了負(fù)壓對抗拔承載力的影響，為桶形基礎(chǔ)在這1地區(qū)的使用提供了1定的參考。
[關(guān)鍵詞] 桶形基礎(chǔ) 抗拔承載力 負(fù)壓 模型試驗(yàn)The study on pull-out bearing capacity of bucket foundation is introduced in brief,and the foundation used to model test is made according to the conditions in which the bucket foundation will be used. In order to find out the pull-out bearing capacity of bucket foundation in soils of offshore area, the study on pull-out bearcaning capacity of bucket foundation is made by using models with different depth, and the mechanism of pull-out bearing capacity is analyzed considering the effect of suction on pull-out bearing capacity. The results can be reference when the bucket foundation is used.
Keywords: bucket foundation; pull-out bearing capacity; suction; model test
