Numerical Simulation Analysis On The Anchor Bolts Under Simple Harmonic Wave

As an important branch of geotechnical engineering, anchoring technique is widely used. Anchoring technique is that setting anchor bolts through layers, structures and layers are tightly combined. In this way, layers are strengthened by the connection of anchor bolts and surrounding layers, maintaining the stability and integrity between structures and solid. Anchoring technique is beneficial to safety of construction due to sufficient improvement of the strength of solid and self-stability; therefore it is one of the most economical and effective measures to solve complicated problems associated with geotcchnical engineering.Recently, however, the majority ol’geotechnical anchoring techniques are based on the research and design theories of static, merely related to the research of dynamics of earthquake. This essay will focus on dynamic problems in anchoring engineering. The correct numerical stimulation will be acquired by the numerical analysis of monochromatic dynamic loads and the comparison of existing and latest experiment. There is also a research of the impact of the load frequency to the strain of anchors.Based on the existing research, the major issues of this essay are listed below:(1) The domestic and international research of anchoring will and the recent field of application will be introduced, as well as some problems of research of anchoring. The major research content, the meaning of the research and the expected goals will also be addressed.(2) Employing ABAQUS. a kind of so ft ware working with finite element, conditions of the experiment are stimulated in the field of elasticity, and the discipline of the variation of the strain of the reference point of anchoring bolts by the lime will be addressed.(3) Comparing the model and the experiment, the analysis of factors of causing errors, the demonstration of correctness of the stimulation will be completed, providing an accurate model of following researches.(4) In the model which is demonstrated to be correct, applying dynamic loads in different frequencies, anchoring strains will be analyzed. Consequently, the discipline of the impact of frequencies to the anchoring bolts and the weakness of this essay will be concluded. There will be some advices on the research of the structure of anchors under dynamic loads.Along with the development of the numerical stimulation of anchoring and the continuous expansion of the application, the conclusion acquired in this essay will provide theories of designation and calculation of anchoring under dynamic loads.
