Influence Analysis of the Design Parameters of Anchor Cable on the Diversion Wall Reinforcement with Prestressed Anchorage on Complicated Foundations

预应力锚索加固是一种比较成熟的岩土加固技术,已广泛应用于许多工程,同时预应力锚固是改善结构稳定性的重要手段。基于ANSYS有限元软件进行模拟计算,利用预应力锚索加固复杂地基导流墙,研究了锚索设计参数对复杂地基导流墙预应力锚固的影响,提出针对台阶状复杂地基的布锚方式。结果表明:锚索设计参数对复杂地基导流墙预应力锚固有不同程度的影响,导流墙的侧向抗滑稳定对锚固角、锚固高程及锚固间距的变化极其敏感,锚固效果受锚固高程的影响最为显著。

Prestressed anchor cable have been widely used as a main reinforcement method in many project cases ,mean-while ,it’s also an important approach to improve the stability of structures .According to the ANSYS simulation ,pre-stressed anchor cables were adopted to reinforce the diversion wall on a complicated foundation .the influence of design parameters of the anchor cables was studied in detail .In view of the stepped complicated foundation ,the arrangement of the anchor cables was put forward .The results indicate that the design parameters of anchor cables have different effects on the diversion wall reinforcement with prestressed anchorage on complicated foundations ,the lateral anti-sliding stability of the diversion wall is extremely sensitive to the change of the anchorage angle ,altitude and interval space of the an-chors ,with the anchorage altitude posing the most significant impact on the anchoring effects .
