针对在建的广东省某油气化工程项目中码头桩基在挖泥船清除群桩之间淤泥产生的水平荷载作用下的安全问题
运用有限元方法进行了实体模拟.分别建立了梁单元模型和弹性半空间地基模型
计算了在水平荷载作用下钢管混凝土复合灌注桩危险截面的弯曲应力、切应力以及桩顶的水平位移
校核了桩基的强度和刚度.结果表明:桩基在受到清淤船的水平碰撞力作用下
允许承受的最大水平荷载和最大水平位移均满足现有规范的要求
桩基不会受到任何损害.研究方法和研究结果可为工程建设部门和设计单位等提供决策依据.
In allusion to the safe issue of piles under horizontal load induced by a dredger that eliminates sludge among clump of piles of a wharf in a Guangdong Oil-gasification Project under of construction
the solid simulations were performed by using Finite Element Method.The beam element and elastic half-space foundation models were established
respectively
to calculate the bending stress and shear stress on risky sections and the horizontal displacement for cast-in place piles combined by steel tube and concrete under horizontal load
and the strength and stiffness of piles were checked.The results show that the maximum horizontal load and displacement of adaptive capacity for piles under horizontal collision force induced by the dredger satisfy the existing code requirement and piles do not suffer any damage.The present methods and results of study can provide the decision-making basis for engineering construction department and design institute
