摘　　要：针对以分道通航制为主的船舶定线制没能解决各主要交通流汇集区域的船舶会遇问题,结合我国船舶定线制发展的特点,分析了交通冲突技术应用于船舶定线制警戒区安全研究的有效性,提出了一种以水上交通冲突技术(VTCT)和灰色聚类为理论依据的船舶定线制警戒区交通安全评价方法。应用该方法,对宁波-舟山港核心港区深水航路船舶定线制的共4个警戒区及1个环形通道的交通安全状况进行评价,评价结果为安全诊断和优化船舶定线制的设计方案等提供了依据。The conventional methods,which are based on limit equilibrium approach,commonly used in the design of anchored sheet pile walls do not consider the method of construction.However,the influence of construction method in real projects is usually significant.A series of physical model experiments are conducted using both excavation and backfill methods to measure some of the parameters reflecting the behavior of sheet pile walls,including wall deformations,wall bending moments,and anchor forces.The study results indicate that walls constructed by backfill method yield significantly higher bending moments and wall deformations,but lower anchor forces.
