斜坡堤次护面块体的稳定性研究Ⅱ

Stability of minor armor blocks for rubble mound breakwaterⅡ

通过两个断面的模型试验,进一步研究次护面块体的稳定性.试验断面1次护面块体位于静水面下1.5倍波高H13％的坡面,断面2次护面块体位于静水面下1.5倍波高H13％的肩台上.试验波浪范围分别为H/d=0.11 ～0.14和H/d=0.09～0.11.试验发现,肩台上护面块体的稳定性较坡面上护面块体的稳定性差.从试验结果得出以下结论：1）位于静水面下1.5倍波高处及以下坡面的护面块体,其稳定重力为主护面块体稳定重力的1/3;2）位于静水面下1.5倍波高肩台处的护面块体,其稳定重力为主护面块体稳定重力的0.9倍.

The minor armor blocks are stability of minor armor blocks are studied further based on two types of model tests. The positioned on the slope 1.5 times H13% under the MWL in test 1, and on the berm 1.5 times H13% under the MWL in test 2, with H/d = 0. 11 - 0. 14 and H/d = 0. 09 - 0. 11 respectively. It is found that the stability of armor blocks on the slope is better than that on the berm. Following conclusions are drawn from the tests： armor blocks.
