Research On The Numerical Simulation Of Anchor Mechanism And It's Application On Engineering

The pre-stressed anchor technology is most highly effective and the economical reinforcement technology, therefore obtained all the various trades and occupations highly to take with the rapid development. However until now the fundamental research still fell behind the actual project application, has such as the pre-stressed anchor effect still not to be clear about, under long-term anchor function anchor cable pre-stressed loss rule, the pre-stressed size to reinforces effect influence and so on question. Therefore to the anchor theory thorough discussion and the research, to impels the crag earth project do main the development to have the extremely vital significance.Making use of finite element method software ADINA to carry out the anchoring effects on prestressing force anchorage cable imitates. With the simulated load, the cable stress distributed rule of anchor solid along anchor, and anchoring in different length, different materials such as geotechnical conditions anchorage distribution of stress; Through the value computation, has obtained the pre-stressed anchor cable axle strength, the shearing stress along in anchor section length distributed rule, provides the certain theory basis for the reasonable design anchor section length..Union project example, model and finite element method numerical value analysis carrying out physics on to excavating the side slope load-off and add anchors. Change anchorage cable the length, dip angle, location etc. working out finite element method calculation procedure, anchoring the slope of optimized design. Finally indicate: The length, location have direct impact to the maximal level displacement that the side slope excavates, there exist a best range in dip angle, design the data being under construction providing the reference coming to a few have value for side slope the days to come adds an anchor.Finally, some problems need to further research in the future is discussed.
