作用在重力式码头上的荷载主要是填土和地面活荷载产生的主动土压力;维持结构物稳定的则是结构物自重和一部份填土重。因此,增加重力式码头的稳定性、降低码头造价的途经是减少主动土压力和最大限度利用填土的重量。在码头墙后方回填内摩擦角大的材料如块石做成减载棱体可以大大减少主动土压力;采用衡重式挡土墙结构也能减 The load acting on the wharf is mainly active earth pressure generated by filling and ground live load; the structural stability is maintained by the self-weight of the structure and a part of the filling weight. Therefore, increasing the stability of the gravity wharf and reducing the cost of the wharf will reduce the active earth pressure and make maximum use of the fill weight. The backfill of materials with large internal friction angle, such as stone blocks, to reduce the load on the back of the wharf wall can greatly reduce the active earth pressure; the structure of the counterweight retaining wall can also be reduced
