摘要
针对某一新型水下井口基盘,进行了室内模型试验,包括准静态试验和模态试验,并和有限元计算结果进行了对比。考虑了冰载荷、波浪载荷、流载荷、地震载荷对结构的作用,试验给出的平台应力、位移响应、振型、频率和有限元计算的结果一致,此井口基盘结构是安全的。
According to a new subsea wellhead base structure,a model test including static test and mode test carried out. Also the test results are compared with the numerical results from FEM. The ice load, wave load, current load and earthquake load are taken into account in the structure. The stress, displacement, natural frequency from test are consistent with the results of FEM. And the safety of the present subsea wellhead base structure is confirmed.
