Graded broken stone preparation method for surface layer of high-speed railway foundation bed and graded broken stone
The invention discloses a graded broken stone preparation method for a surface layer of a high-speed railway foundation bed and graded broken stone. The preparation method comprises the following steps: primarily selecting the grading of the graded broken stone according to requirements; carrying out first-stage performance verification and adjustment on the graded broken stone corresponding to the preliminarily selected graded pair; judging the structure type of the adjusted graded broken stone, and calculating a grading curve of the graded broken stone; comparing the grading curve obtained through calculation with a primarily selected grading curve, and carrying out secondary adjustment; carrying out second-stage performance verification, judging whether a verification result meets a preset requirement or not, and if so, ending the grading preparation; and if not, returning to the step of first-stage verification and adjustment. The graded broken stone obtained by the preparation method has the advantages of good permeability, compaction performance and the like, and can effectively prevent and treat frost heaving diseases on the surface layer of a high-speed railway foundation bed in a severe cold area.
一种用于高速铁路基床表层的级配碎石配制方法及级配碎石，所述配制方法包括步骤：根据需求初步选定级配碎石的级配；对该初步选定的级配对应的级配碎石进行第一阶段性能验证并调整；对调整后的级配碎石进行结构类型判断，计算其级配曲线；将所述计算所得的级配曲线与初步选定的级配曲线进行对比，并进行第二次调整；然后进行第二阶段性能验证，判断验证结果是否满足预定需求，如果满足，则级配配制结束；如果不满足，则回到所述第一阶段验证和调整的步骤。该配制方法得到的级配碎石具有良好的渗透性能、压实性能等特点，并可有效防治严寒地区高速铁路基床表层的冻胀病害。
