省道改建公路软基施工处治技术研究

Research on the Treatment Technology of the Soft Foundation Construction of the Provincial Road Reconstruction

摘要: 土工格栅加筋材料具有抗拉变形模量大、强度高、韧性好、与土颗粒间的摩擦系数高、联锁作用强等特点。将其与各种粗粒土混合形成加筋垫层，用于软弱地基加固补强，可有效提升地基承载能力，减小沉降。基于此，本文结合某省道改建软基加固工程，提出了土工格栅加筋碎石垫层施工方案，以期全面提升工程质量。

Abstract: Geogrid reinforced materials have the characteristics of large tensile deformation modulus,high strength, good toughness, high coefficient of friction with soil particles, and strong interlocking effect.It is mixed with various coarse-grained soils to form a reinforced cushion, which is used to strengthen and strengthen weak foundations, which can effectively improve the bearing capacity of the foundation and reduce settlement. Based on this, this paper, combined with a soft foundation reinforcement project of a provincial road reconstruction, proposes a geogrid-reinforced gravel cushion construction plan, with a view to comprehensively improving the quality of the project.
