Slope Anchor Technology Research And Application

Anchorage technology is an important means of reinforce in the geotechnical engineering. It has showed more and more hearty vitality in the area of reinforce in the geotechnical engineering as its unique effect, simple and convenient technology, far-flung application and economical cost in recent years. At the present time, it has not only been used in the mine but in the areas of metallurgy, water conservancy and hydroelectric power, railway and highway, civil construction and so on and has good foreground of application. So, the research of anchorage technology has very important meaning.All kinds of stress of the anchor in the concrete has been investigated firstly according to the anchorage function in rock side-slope, for example, the axial and the shearing stress distributing character of the anchor and side-slope protecting condition of the combined effect of the anchor and the concrete. At the same time, the reinforced mechanism of the pre-stress cable and the stress distributing character of its anchor segment have been specially investigated and the pre-stress cable were expected to be applied effectively in protection of the side-slope.According to the complexity of side-slope system and its variety of influencing factors, the influencing degree of all kinds of influencing factors, the material, configuration, the mode of reinforce of the anchor, the property of the rock-body, the anchorage parameter and etc, have been studied in order to find out their influencing degree. At last, the reasonable and effective protecting methods are to be applied according to the main influencing factor.The distortion mechanism of rock body was analyzed by cybernetics of configuration of rock body and the structural mechanics effect of rock body according to investigating the character of rock body including its rigidity and jointing constructional surface and the condition of stress of the rock-body in the side-slope was improved according to the anchorage function in anchorage system of the side-slope, which provide a new route for the protecting side-slope.At last, the ANSYS software of finite element analysis has been applied to simulate and analyze the stability of the side-slope of the highway according to the investigation of its geology condition. The pre-stress cable and the strengthened beams were selected and applied to reinforce the side-slope based on the analysis result. Then, the reinforce project and the stress of the pre-stress cable have been simulated by the ANSYS, which have not only good effect but validate the anchorage mechanism in the former chapter.
