库水位循环作用下架空斜坡式码头变形研究*

为研究山区河流库水位循环作用下码头结构变形特点,依托云南省富宁港一期工程,建立架空斜坡式码头三维有限元模型.以水岩相互作用为基础,重点研究库水位循环作用下架空斜坡式码头整体变形特点、桩基水平位移、桩顶沉降、挡土墙失稳模式；得到码头结构物变形发展趋势,同时预测架空斜坡式码头在库水位循环作用下的破坏方式,为进一步研究山区河流码头结构与库岸边坡相互作用及其时变特性提供基础.

Deformation of overhead sloping wharf under water level cycles

In order to research the wharf structures deformation characteristics under water level cycles circulation in the mountain rivers, the paper relies on the first-stage project of Funing port in Yunnan Province and establishes a three-dimensional finite element model of the overhead sloping wharf. Based on the waterrock interaction, it mainly studies the overall deformation characteristics of overhead sloping wharf, the horizontal displacements of piles, the piles top settlements and the retaining wall instability mode under the water level cycles circulation. It also obtains the wharf structures deformation development trends, meanwhile, the paper predicts the failure modes and features of overhead sloping wharf under the action of water level changes. The results can provide a reference for further studying the interaction between wharf structures and bank slope located in the mountainous rivers and its time-varying characteristics.
