| 摘 要： | 从土工格栅加筋垫层的作用机理出发,根据太沙基理论着重介绍了格栅加筋垫层承载力的两种计算方法,并提出考虑格栅垫层各向异性特性、垫层厚度和扩散角等因素影响的加筋垫层下竖向应力经验的计算公式,最后参照日本经验给出了土工格栅垫层厚度的设计方法。

| Abstract: | Starting from the action mechanism of geogrid reinforced cushion and according to Terzaghi theory,the author introduces two methods to calculate bearing capacity of geogrid reinforced cushion,proposes computing formula of vertical stress under reinforced cushion influenced by anisotropy characteristic of geogrid cushion,thickness of cushion and angle of spread,and puts forward the method to design the thickness of geogrid cushion according to Japanese experiences. |
