液化土中水平承载桩动p-y曲线研究
|
摘要
针对土层液化后承载力降低问题,分析了大量的国内外研究资料,综合论述了在振动荷载作用下桩-土相互作用的有关理论研究和试验成果,并提出了需要进一步研究的问题,为横向动荷载作用下海洋桩基平台的设计研究提供必要的理论依据。
Strength reduction in liquefied soil is discussed based on the analysis of plentiful work at home and abroad,the related theories and test results on pile-soil interaction are dissertated by synthesis,and contents are put forward to lucubrate.The results will be beneficial to designs of offshore platform under lateral dynamic load.
