摘要
为研究棚洞垫层厚度对落石冲击影响,首先利用ABAQUS有限元软件建立了落实冲击棚洞模型,针对棚洞垫层厚度与冲击深度、最大冲击力进行了分析,并探讨了棚洞垫层的合理厚度,研究提出的棚洞垫层厚度,建议值,为后续落石防护提供理论基础,对强风化边坡区域的落石防护方面的研究应用具有重要的理论参考价值。
In order to study the influence of shed - tunnel cushion thickness on rockfall, first, the ABAQUS finite element software was used to establish the model of rockfall impact tunnel. Then the thickness, impact depth and maximum impact force of cushion hole were analyzed, and the reasonable thickness of cushion was discussed. The recommended value of the thickness of the caving cushion proposed in this study provides the theoretical basis for the follow - up rockfall protection, which has important theoretical and practical significance for the research and application of the rockfall protection in the strong weathering slope area.
