联排桩结构在航道高边坡直立式驳岸上的应用

Application of row-pile structure in waterway high-slope upright revetment

针对岩层埋藏较浅的高边坡支挡结构,基于荷载结构法,根据弹性地基梁理论对模型进行合理的简化,将阻滑桩基由分布式结构优化为联排桩结构,充分发挥入岩段联排桩的固端作用,减小单桩的内力和变形,同时减少对周边建筑物的干扰,降低入岩桩基施工难度。

For high-slope retaining structures buried in the shallow rock, based on the load structure method,the model was reasonably simplified according to the theory of elastic foundation beam.The anti-skid pile foundationwill be optimized from the distributed structure to the double-row pile revetment structure, which can play fully therole of end-fixing of raw-pile in the rock section, reduce the pile internal force and deformation, and reduce theinterference with neighboring buildings, so as to reduce the construction difficulty of the pile into the rock.
