OOFE Software Development Of Laneway Supported By Bolting

Anchorage technology is an important means of reinforce in the mine engineering. Presently, though there are many calculating model of anchor-bolt and many research results concerning these problems, there exist some problems on these methods in simulating the anchor bolt's mechanical behavior. The spar bolting model only can reflect the longitudinal stiffness but not able to reflect the shear stiffness. So, this thesis adopts spar-beam model which can not only reflect the longitudinal stiffness but can reflect the lateral stiffness of the bolting. Also, it could consider the pre-stress of the bolting and could simulate the interaction of the bolting and rock in a reasonable way. Then, the object-oriented programming concept is applied to finite element method. Based on the static analysis and dynamic analysis of the laneway support by bolting, the author developed "Object-oriented finite element analysis system software of the laneway supported by bolting". It overcomes the reusable and maintainable defect of traditional finite element procedure. This software has friendly man-machine interface and certain pre-processing and post-processing function. After static analysis, the distortion and the stress of the rock can display in from of graph and data. Meanwhile, we can easily inquire to the displacement of node. After dynamic analysis, the deformation and the vibration of the laneway can be displayed. Also, the dynamic curves of node displacement and velocity and acceleration can be given out. Finally, the software is validated through the example and a dynamic response instance of the laneway under the seismic load is given out.
