插砌条石护面防波堤的试验研究

本研究首先对防波堤护面斜缝插砌和平缝插砌两种结构型式进行了力学分析，得到了条石临界稳定的力学平衡基本关系式；再通过40多种结构断面模型和1380组次的波浪模型试验，对影响条石护面厚度的有关因素进行了无因次分析；最后提出了确定插砌条石护面厚度的计算公式，为工程设计提供了必要的依据。同时，还提出了关于制订防波堤设计规范的试验成果及其分析意见。

A TEST OF PITCHING BREAKWATER WITH RECTANGULAR SLAB STONES

The mechnical analysis was made to two types of structure modelsof oblique and plane seams pitched with rectangular slab stones, in regard to the condi-tions of waves and water flows, thus the basic mechanical equilibrium relationship ofcritical stability of stones was obtained. On the basis of 40 varied structure sectionmodels and 1,380 times of wave model test was then made non-dimension analysis ofrelevant factors which may affact the thickness of pitched stones. As a result, thecalculation formula for determing the thickness of building pitching stones were putforward, which may provide a theoretical framework for engineering design of break-waters. Besides, some experimental results about the standard for breakwater design aswell as some analytic ideas were also provided in this paper.
