超长桩在大型桥梁和高层建筑中得到了越来越广泛的应用,实际工程中往往会出现桩越来越长的现象,有时桩太长会造成浪费,且不科学,所以有必要研究超长桩的有效桩长问题。作者运用数学和力学知识,在假定计算模型的基础上,从理论上推导了超长桩的有效桩长计算公式。这对软土地区超长桩的设计有着重要的指导意义和适用价值。
Ultra-long piles in large bridges and high-rise buildings have been more and more widely used, the actual project often appear longer and longer pile phenomenon, and sometimes too long pile will result in waste and unscientific, it is necessary to study the super Effective long pile length problem. Based on the assumption of calculation model, the author derives the effective pile length calculation formula of super-long piles theoretically by using mathematical and mechanical knowledge. This has an important guiding significance and applicable value to the design of super long pile in soft soil area.
