【摘要】 在对常规方法和潮汐河口岸滩水力特征分析的基础上,提出将杩槎群用于潮汐河口深泓固脚护岸的思路,通过室内试验,分析了杩槎的布置形式、抛投方式、架空率对减速率的影响及杩槎群缓冲落淤作用。表明杩槎可以推广应用于以往复潮汐流为特征的深泓护岸和保滩,具有经济、易实施、便于维护的特点。更多还原

【Abstract】 Based on analysis of the conventional methods and hydraulic characteristics of the coast in a tidal estuary,the feasibility of using abatis in beach protection engineering of tidal estuaries is studied.Through laboratory tests,the layout of abatis,the casting methods,and the effects of the overhead ratio on the deceleration rate,buffering and sedimentation are analyzed. The results show that abatis can be applied to bank protection and beach protection where a reciprocating tide exists.The method is economical,easy to implement,and easy to maintain.更多还原
