基于水平钢架的全直桩系缆结构优化设计

与传统斜桩结构相比,全直桩结构完全以自身抗弯能力来承受水平荷载,在相同受力条件下存在桩径大、竖向承载力没有充分发挥、工程投资偏高的特点.针对该问题,提出一种新型含水平钢架的全直桩结构,以某工程系缆墩为例,采用空间模型进行计算分析,确定优化结构方案,并在该结构的桩基中间位置利用水平钢架与桩基进行连接.结果表明,增设水平钢...

Optimization of all-vertical-piled mooring pier based on horizontal steel truss

Comparing to the conventional oblique pile,all-vertical-piled structure bears the horizontal load completely by its own bending resistance,the pile diameter is larger,the vertical bearing capacity is not fully developed and investment is higher under the same stress condition.Aiming at this problem,we propose a new type of all-vertical-piled pile structure with horizontal steel truss,take the certain engineering mooring pier as an example,use the space model for calculation and analysis,and determine the optimal structure scheme,and apply the horizontal steel truss to connect the pile foundation in the middle position of pile foundation.The results show that adding horizontal steel frame can increase structural stiffness,reduce pile diameter,control structural displacement,give full play to the role of rock socketed pile,and has obvious economic advantages.
