摘　　要：为探究三类浆砌片石结构与格构组合在护坡中的支护特性,通过建立三种不同材质(石英砂岩、多孔玄武岩、花岗岩)浆砌片石结构与格构组合的三维数值模型,分析格构梁在荷载作用下的位移、应力应变情况,以及格构梁搭接长度对结构受力位移情况的影响。研究结果表明:(1)内嵌花岗岩浆砌片石结构的格构组合在抵抗位移和应力方面表现最佳。(2)考虑格构配筋时,可在节点与跨中部位适当增加配筋率。(3)格构梁经济高效的搭接长度范围为110 mm至130 mm。该研究结果可为格构式浆砌片石护坡结构的工程实践提供参考。In order to explore the supporting characteristics of three types of masonry schistose structure and lattice combination in slope protection,a three-dimensional numerical model of three different materials(quartz sandstone,porous basalt,granite)masonry schistose structure and lattice combination is established.The displacement,stress and strain of lattice beam under load,and the influence of the lap length of lattice beam on the force and displacement of the structure are analyzed.The results show that:(1)The lattice combination of the embedded granite mortar rubble structure performs best in resisting displacement and stress.(2)Considering the lattice reinforcement,the reinforcement ratio can be appropriately increased at the joints and mid-span.(3)The economical and efficient lap length of lattice beams ranges from 110 mm to 130 mm.The research results can provide reference for the engineering practice of lattice mortar rubble revetment structure.
