洪家渡2号塌滑体加固抗滑桩及锚固洞有限元内力分析

工程中常用的抗滑桩和锚固洞的内力计算方法多为地基系数法．该法只能将抗滑桩和锚固洞分开考虑，对于抗滑桩和锚固洞的联合结构，该法不能反映它们的相互作用和联合受力状况．为了正确反映锚固洞桩的受力状态，提出一种滑坡体加固构件有限元内力分析方法，并应用于洪家渡2号塌滑体加固构件——抗滑桩及锚固洞的有限元内力分析，从而为加固构件的配筋设计提供了可靠依据．

Finite element analysis of internal forces in anti-slide piles and anchor caverns for reinforcement of Hongjiadu No.2 landslide body

The ground coefficient method is commonly used for internal force calculation for anti-slide piles and anchor caverns. Owing to its separate consideration of the internal forces of the two parts, the method cannot reflect the interaction between the anti-slide piles and anchor caverns and the combined stress state of the associated structure. For reasonable reflection of the stress state of the associated structure of anti-slide piles and the anchor caverns, a finite element internal force analysis method is proposed and applied to analysis of the internal forces of the reinforcing components of the Hongjiadu No.2 landslide body. The result provides a rational basis for reinforcement design of landslide reinforcing components.
