渐近均匀化方法在土钉支护变形中的应用

Application of homogenization theory to deformation analysis of soil nail support

利用FLAC-3D建立模型,结合渐近均匀化方法求得了土钉和土组合成的复合体的等效模量,并对土钉支护的变形性能进行了分析.通过与实测结果的对比,验证了采用渐近均匀化方法对土钉支护变形进行分析是可行的.

Asymptotic homogenization theory is applied to calculate equivalent elastic modulus of the reinforced area of soil nails and soil into complex.By establishing a simulation model using FLAC-3D and combining with the equivalent elastic modulus,the displacement performance of soil nailing is analyzed.Compared the results with field measured results;the method is feasible.
