Pile-supported reinforcing method considering accumulated settlement of embankment under local cyclic load
The invention discloses a pile-supported low-embankment reinforcing method considering accumulated settlement of an embankment under a local cyclic load. The pile-supported low-embankment reinforcing method comprises the steps that a pile-supported low-embankment numerical model considering accumulated settlement of the embankment under the local cyclic load is established; performing dynamic analysis on the numerical model; and on the basis of calculation results of accumulated settlement of the embankment under different parameters, optimizing design parameters such as the position, the strength, the number of layers and the height of the embankment of the reinforced body, and carrying out optimization design of the pile-supported low embankment under the action of the traffic load. According to the method, modeling fits engineering practice, engineering optimization design is guided on the basis of the principle of reducing accumulated settlement of the low embankment, and the long-term service performance of the pile-supported low embankment under the traffic load is improved.
本发明公开了局部循环荷载下考虑路堤累积沉降的桩承式低路堤加固方法，包括：建立局部循环荷载下考虑路堤累积沉降的桩承式低路堤数值模型；对数值模型进行动力分析；基于不同参数下的路堤累积沉降计算结果，优化加筋体的位置、强度、层数和路堤高度等设计参数，进行交通荷载作用下桩承式低路堤的优化设计。本发明建模贴合工程实际，基于减小低路堤累积沉降的原则指导工程优化设计，提高桩承式低路堤在交通荷载下的长期服役性能。
