摘　　要：绝大多数内河码头在建成使用初期岸坡处于稳定状态,但在水流作用下岸坡前沿河床地形可能随时间发生改变,导致岸坡变形滑移使码头结构发生变位甚至随岸坡发生整体滑移。结合某工程实例,分析该高桩码头岸坡因河床演变导致变形并使码头结构发生变位的主要原因,研究使该码头岸坡恢复稳定的工程措施,并总结因河床演变导致码头岸坡变形滑移的预防和整治措施。Most river dock slopes are steady at the early stage of its application,but the river bed topography in front of the slope may change over time under the action of current,resulting in the deformation and sliding of the slope,which leads to the displacement or even overall slipping of the dock structure.Based on an engineering case,this paper analyzes main causes of the deformation and structure displacement of a piled dock due to the bed evolution,probes into the engineering measures for restoring the stability of the slope,and studies the prevention and remediation measures for the deformation and sliding of dock slope due to the bed evolution.
