深水防波堤堤心石级配调整试验

由于石料源头及堤心石堆场有限,造成堤心石堆高后细颗粒含量增加,堤心石质量难以满足合同及技术规范要求,因此,采取加强石料源头控制等措施以达到堤心石级配要求。为从根本上减少堤心料的筛分量,保证防波堤的施工进度,通过设置中间层、调整堤心石质量级配方法,进行相应断面模型试验验证,为防波堤工程的顺利实施提供技术支撑。

Experiment on grading adjustment for quarry run of deepwater breakwater

The quarry run quality is difficult to meet the requirements of the contract and technical specification because of the increase of fine content caused by high quarry run stock, so we strengthen the source control of the quarry run to meet the grading requirements. To minimize sieve quantity of quarry run on site, and ensure the construction progress of breakwater, we verify the section model test through setting the middle layer and adjusting the grading of the guarry run to provide a technical support for the breakwater engineering.
