以方形结构网箱的单箱体型锚泊系统为研究对象,通过力学分析和程序计算得出锚绳张力以及不同来流角度下的阻力系数之和(SRC)两项安全性能指标。结果表明,在理论的最危险受力情况下,单锚绳系统中锚绳张力的最大值为网箱阻力R,在双锚绳系统中则小于R。当双锚绳系统的锚绳安装角度β设置在最佳值22.5°时,SRC获得最小值34.65,该值相比β=1°时的SRC(39.59)下降了约12.5%,相比单锚绳系统的SRC(41.36)则降低了16.2%。
Taking the single-box type anchoring system with square structure cage as the research object, two safety performance indexes (SRC) of anchor rope tension and sum of drag coefficient at different flow angles are obtained through mechanical analysis and program calculation. The results show that the maximum cable tension in a single mooring rope system is the resistance R of the cage and less than R in the double mooring rope system under the most dangerous stress in theory. When the anchor rope installation angle β of the dual-mooring rope system is set at the optimal value of 22.5 °, the SRC obtains the minimum value of 34.65, which is about 12.5% lower than that of the SRC (39.59) at β = 1 °. Compared with the single anchor The rope system SRC (41.36) is reduced by 16.2%.
