摘　　要：在现有海底管线抗震规范的基础上 ,根据海底铺设环境的实际情况 ,在考虑管线惯性力影响的情况下 ,提出了管土动力响应的新的力学模型 ,侧重分析引入惯性力与土壤滑移的影响 ,结合实际工程参数 ,对考虑惯性力后的动力学方程进行了仿真计算 ,比较了引入和不引入惯性力两种抗震设计方法的结果 ,这对海底管线的抗震设计有一定的参考和实际应用价值。Based on the existing criteria of earthquake-resistant design of subsea buried pipeline, new pipe-soil interaction models are given according to the working environment of subsea pipeline. The influence of inertia force of pipeline and soil property are emphasized in the models. The models are simulated with the parameters of practical project. Comparing with the models not considering these two factors, the new models are more reasonable and valuable for designing subsea pipeline.
