海洋采油平台打桩工程中土塞效应研究
|
摘要
根据太沙基深基础计算方法提出新的土塞效应判断方法,考虑边载效应,同时考虑打桩对周围土体的影响,引入动力效应系数,并将其应用于实际工程中,实测打桩记录结果与计算结果吻合较好,可用于桩的可打入性分析。
Based on the Terzaghi′s bearing capacity theory for deep foundations,a new approach for soil plug assessment is put forward,in which the surcharge effect and the influence of driving piles on surrounding soil have been considered;and the dynamic effect coefficients are included. The approach has been applied to practical engineering projects;and the calculated results agree with the observed data very well,indicating that the approach can give more reasonable results than the currently used method.
