Contrastive Study Of Sectionalized And Wholly Grouted Anchor Load Transfer Machanism

For recent years,with the construction of traffic engineer in western years, stability analysis and reinfoercement method research is becoming more and more important. Anchorage technology has been one of the most effective and the most economic methods to resolve complex problem in geptechnical engineering, as it is to utilize subtly the higher tensile strength of steel and can transfer or enhance intensity and steady ability of rock and soil, what's more, it decreases the cost of engineering and is beneficial to the safety of construction. Therefore, to improve the form of anchor arm and study deeply load transfer machanism of achor has very important theoretic and engneering value.This artile bing forward a new mathod of anchorage- sectionalized anchor, contrastive study of its load transfer machanism was accomplished.The main points are as following:1. Based on the collection of research data both at home and abroad the research present about the anchor's load transfer mechanism is summarized,and a new method of anchorage is bring forward.2. Based on the theory of elasticity mehanics and some hypothesis, research of distribution of the stress in anchorage segment of fifferent types of cables is discussed. 3.3. The model based on uplift effect and model based on R.Mindlin solution of displacement are applied to analyze the distribution of the stress of wholly grouted anchor. Combine the solution of wholly grouted anchor with the anysis of the numerical simulation sofeware and the data of experiment ,set forth the emprical formula of sectionalized anchor by the mathematics statistics. The regularities of stress-strain distribution in anchor arm and mortar of two types anchor is summarized by the exerimental research;.it provides the reality basis for theoretical solution.4. On the proper plane model, simulation of prestressed cables by using the numerical simulation software ANSYS ,a conclusion of campatibility was drawn from examination and certification by ansysticial calculutions and experimental results.The anchorage theroy in geo-technical engneeing is important constituent of the application and development of anchor technique, reliabletheoretical basis for theoretical analysis, A significant reference fuction is provied from the research finding obatined in this study.
