Recently, necessity for restraining the movement of the anchored structures has increased regarding the settlements of adjacent existing structures. Conventional design methods and irrelevant finite element analysis would not be pertinent to predict the movements of the anchored system.
Aims of this research are to examine the applicability of improved finite element method, to study the effects of various parameters on the behaviour of anchored structures, and to suggest a optimized design technique for anchored structures. The soil was modeled by various elatoplastic constitutive relationships, such as Hyperbolic model, Drucker-Prager model and Cam-Clay model.
The conclusions obtained are as follows:
1. The conventional design methods should be improved in aspects of expenses and efficiency.
2. The improved finite element method is applicable to predict the movement of actual field cases.
3. Numerical analysis accompanying the field measurements could make the design more economical and efficient.
