摘　　要：作为滨海电厂拦污网的锚定基础,方块重力式结构由于施工相对方便、造价较低、且可兼做堤头灯基础等原因而被较多采用。由于重力式锚定基础对波浪传播有较大影响,在极端工况下影响防波堤块体的稳定性。通过波浪物理模型试验,开展锚定基础结构优化研究。结果表明,采用弧形的锚定结构可显著减少对波浪的反射,适用于设计水位较低情况;桩基透空式结构可有效降低对波浪传播的影响,从而保证防波堤块体在增加锚定基础后仍保持稳定。As the anchor foundation of trash-intercept net of Binhai Power plant,gravity block structure is widely adopted due to convenience in construction,low cost,and its function serving as the foundation of dike-end lamp.gravity anchor foundation influences wave transmission greatly,even the stability of armor blocks under extreme conditions.Thus structural optimization of anchor foundation is studied through physical model experiment.The results show that arc-shaped anchor foundation can significantly reduce the reflection against wave,apply to lower design water level.In addition,permeable pile foundation effectively lowers the impact on wave transmission so as to keep armor blocks stable subject to the addition of anchor foundation.
