斜坡式防波堤堤心石动力特性试验研究

我国现行规范规定防波堤堤心材料为重量10～100 kg之间的块石,但实际工程往往很难达到这一重量范同的标准.如果利用重量范隔更大(如:1-800 kg)的块石作为堤心石,对整个斜坡堤的正常工作影响如何,同前国内对这方面的研究较少.因此,结合深水斜坡堤的丁程实例,利用模型试验,对不同重量范围的堤心石进行动力特性方面的研究.初步结论认为,1～800 kg块石作为堤心石,其动水压强较10～100 kg的值大,而静水压强较小.

An Experiment Study on Dynamic Characteristics of Core Rocks in Rubble Mound Breakwater

The core materials for a rubble mound breakwater are rocks weighing from 10 kg to 100kg as specified in the current standards,but in the practical engineering works,it's hard to reach this standard.If we take a rock which has larger range of weight(say 1~800 kg) as the core rock,how much influence it has on the normal work of the rubble mound breakwater? Few studies have been so far conducted on this aspect.Hence,this paper describes further studies on the dynamic characteristics of the core rock with the different weight ranges,which was based on the sample of a deep water rubble breakwater and model tests.The elementary conclusions indicate that core rock of 1~800 kg has a higher dynamic water pressure but lower static water pressure than the core rock of 10~100 kg.
