Abstract

Abstract: On the base of studying the feature of the recent fluvial process and the changing tendency，the effects of the fluvial process to stability of pre-existing revetment work are mainly studied． The achievements are indicated that the left braided reach will be maintained as the main river reach in Shishou reach during a long period; and the river scouring has been severe after the operation of Three Gorges Reservoir; while，the river regime has no major change． Fluvial process has certain effect on the pre-existing revetment work． The swing of the thalweg，the changes of main flow souring position，the sour-andfill of islands and beaches，and the partial inshore scour hole all let the flows make effect on the pre-existing revetment work，which is adverse to the stability of part of the preexisting revetment work．

Key words: fluvial process, revetment work, stability

摘要： 在讨论石首弯道近期河床演变规律、发展趋势的基础上，分析了河床演变对弯道已有护岸工程稳定性的影响。研究表明: 近期石首河段仍将在一定时期内保持左汊为主汊，三峡工程蓄水运用后该河段冲刷较为剧烈，但河势不会发生重大变化; 河道演变特性对已有护岸工程的稳定性有一定影响，主要表现为主流线的摆动、主流顶冲点的上提或下移、洲滩以及近岸局部冲刷坑的冲淤变化都使水流对已护岸线的冲刷作用产生了影响，从而对部分已护工程的稳定性产生了一定的不利影响。
