由于各种消浪性能良好的异形混凝土护面块体的出现,斜坡式防坡堤至今仍是防波堤主要采用的结构型式之一。斜波堤的设计因海浪本身以及它对斜坡堤作用的复杂性质,使之在很大程度上需通过水利模型试验来加以验证和改进;即使这样,在世界范围内斜坡堤的破坏事件仍在不断的发生。1978年,葡萄牙锡尼斯(Sines)港深水防坡堤 Due to the appearance of various shaped surfacing blocks with good surfacing properties, slope-type slope protection is still one of the main structural types of breakwater. Due to the nature of the waves themselves and their complex nature of the slopes, the design of the dike is largely verified and improved by hydraulic model tests; even so, the destruction of slopes around the world remains Constantly happen. In 1978, the port of Sines in Portugal was covered with deep water
