基于ANSYS的复杂地基面上高导墙抗滑稳定有限元分析

将简单滑动面上的抗滑稳定有限元分析方法加以改进,并推广应用到各种复杂的地基面上,为有限元法计算类似结构的抗滑稳定性提供参考。利用ANSYS建立复杂地基面上高导墙的二维有限元计算模型,计算分析了5种方案下结构的抗滑稳定性,为锚索加固方案的选择和结构安全评估提供依据。计算结果表明:锚索布置应选择侧向倾斜锚索方案,且这种方案下结构在运行期中满足抗滑稳定要求。所采用的抗滑稳定计算方法在工程中得以应用,结果符合实际情况,适用性强,有一定的参考价值。

FEM analysis of anti-sliding stability for high guide wall on complex foundation surface based on ANSYS

Through improving the finite element method of anti-sliding stability on simple sliding surface and applying it to the complex foundation surface so as to provide a reference for the finite element method of anti-sliding stability calculation of similar structure.The paper used ANSYS to establish two-dimensional finite element model of high guide wall on the complex foundation surface,and analyzed the anti-sliding stability of structure with five schemes in order to provide the basis for the selection of anchor cable reinforcement scheme and the safety assessment of structure. The Results show that the scheme of lateral tilt anchor cable should be taken and the structure can satisfy the requirement of anti-sliding stability in run-time under this scheme. The calculation method of anti-sliding stability has been applied to practical engineering and has a strong suitability and a certain reference value.
