研究了具有基本密度剖面和基本速度剖面的密度分层海洋中内孤立波诱导的流场及其对圆柱桩的作用。通过理论分析和数值计算，给出了一般情况和特殊情况下的流场和桩上水动力随时间的演变规律。对南中国海区的几种环境海况进行了数值模拟。此外，还分析了相对密度差、深度比和波浪陡度对最大总力和总扭矩的影响。
The induced flow fields by internal solitary waves and its actions on cylindrical piles in density stratified ocean with a basic density profile and a basic velocity profile are investigated. Some results, such as the time evolution of flow fields and hydrodynamic forces on the piles are yielded both by theoretical analysis and numerical calculation for general and specific cases. Several kinds of ambient sea conditions of the South China Sea are specified for numerical simulation. Moreover, the effects of relative density difference, depth ratio and wave steepness on maximal total force and total torque are analyzed.
