摘要
针对邓肯—张E—B本构模型和强度折减法在土质边坡稳定性分析中应用广泛,对其进行二次开发并嵌入FLAC3D中具有十分重要的意义。利用FLAC3D的二次开发平台,编制本构模型的相应程序,通过三轴数值试验验证了所编制程序的正确性;结合强度折减法求解了某土质边坡安全系数并判断出其潜在滑动面。
For Duncan-Chang e-b model and application of strength reduction FEM in stability analysis of soil slope wide secondary development and its embedded FLAC3D plays a very important. Developing and application of Duncan-Chang E-B model was realized in FLAC3D, of which accuracy wad verified by the analytic solution of load and unload. Safety factor of a soil slope was obtained and the latent sliding surface was identified by this model with strength reduction.
