摘要
为保护琼州海峡海底电缆免受破坏,拟对海底电缆采用抛石保护法。由于海域存在潮流等动力因素,块石沉降过程会发生偏移。文章以通过垂直深入水下的管道完成散抛的块石偏移量为研究内容,根据自然资料、设计资料和重力相似准则进行物理模型试验,通过试验考察了块石偏移量与块石种类、块石尺寸、水平流速和漏斗底高度之间的关系,分析了块石种类、尺寸、流速和漏斗底高度对偏移量的影响。
In order to protect submarine cable deployed in Qiongzhou Strait from potential damages, the rock- fill cover was proposed as the main defending solutions. The rockfill dumped from the rising tube would have a side offset because of horizontal pushing effects from water flow. Based on the gravity similarity criterion and local envi- ronmental hydrodynamic conditions, the hydraulic model tests on offset of rockfill were carried out. Effects of rock types, rock sizes, current velocities and heights of the funnel were investigated.
