视土工格室加筋体为置于Winkler弹性地基上的连续有限长梁,考虑荷载作用下格室体与其上下表面土体之间摩阻力影响,基于传统的弹性地基梁理论,建立出相应的格室加筋体挠曲变形控制微分方程。引入Galerkin法,导出具有对称荷载作用下格室加筋体的挠曲变形、转角、剪力及弯矩的非线性解析解。进而进一步分析探讨了格室体与土体之间的摩阻效应对土工格室加筋体内力及位移的影响。结果表明:水平摩阻效应对土工格室加筋体内力及位移有一定程度的影响。
The geostrophic stiffened body is regarded as a continuous finite length beam placed on the Winkler elastic foundation. Considering the frictional resistance between the cell body and the upper and lower surface soil under load, based on the traditional elastic foundation beam theory, a corresponding Lattice reinforcement body deflection deformation control differential equation The Galerkin method is introduced to derive the nonlinear analytical solution of the flexural deformation, corner, shear and moment of the cell stiffened body with symmetrical load. Furthermore, the influence of the frictional effect between the cell body and the soil body on the internal force and displacement of the geocell reinforced body is further analyzed. The results show that the horizontal friction effect has a certain influence on the internal force and displacement of geocell reinforced body.
