摘要

文摘：本文介绍了具有均匀径向刚度的土工格栅在路基结构中的应用，以保护道碴垫层免受铁路上部结构的损坏。指出了稳定功能作为土工格栅与集料协同作用的关键机制的重要性，它影响着路基承载力的提高、道碴寿命的延长，并确保铺设在防振垫上的道碴的所需操作参数。关键词：机械稳定；六边形地质网格；压载垫下；铁路道床

Protection of under ballast mats against damage Due to loads from railroad tracks

Abstract: The paper presents the application of geogrids with uniform radial stiffness in subgrade structures in the function of protecting under ballast mats from damage caused by the railroad superstructure. The importance of the stabilizing function as a key mechanism of cooperation between geogrid and aggregate was pointed out, affecting the increase of subgrade bearing capacity, extension of ballast life and ensuring the required operating parameters of the ballast placed on anti-vibration mats. Keywords: Mechanical stabilization; Hexagonal geogrids; Under ballast mats; Railway trackbed
