RESEARCH AND APPLICATIONS OF A PLANE BEAM ELEMENT MODEL WITH ONE IS FREE AND ANOTHER IS EMBEDDED

摘要

For the lining structure,in order to ensure the Cooperative Work between the concrete lining and rock,while in a certain extent increasing the integrity of rock,the high strength structural bolts was arranged between the concrete lining and the surface of perpendicular rock.In order to improve the stress conditions of the anchor,tangential deformation constraints was reduced from the anchor actted on the concrete lining.The anchor with free deformation segment was arranged within a certain range of location between the rock and structure interface.In this article,the beam element model that one is free another is embedded at end of the anchor was Derived,it can effectively solve problems of coordination on degrees of freedom between beam and solid elements,there can be applied to calculate the anchor with free segment.This model proved to be strong practicality and high Accuracy by the example,which can be used for practical engineering.
