Prestressed Anchor Rope Beam Force Calculation Method And The Load Transfer Law Theory Research

For researching into a method of internal force calculation and the law of the prestressing anchor rope beam's load transferring in order to coach the design better, multi-means including theoretical analysis and field test and numerical simulatio were adopted in this paper to analyze and study thoroughly. The content and the characotor of this paper mainly include as follows:1. By using the model of double parameter elastic foundation in this paper the traditional method of internal force calculation on prestressing anchor rope beam were modified, the expression of displacement, rotation, bending moment, shear force of arbitrary section on beam were educed according to the beam's displacement differential equation, then the theoretic foundation of structure designing and studying the law of the prestressing anchor rope load transferring was laid.2. By using the half space theory of the elasticity and the inference the law of stress and displacement distributing after loading in the earth were analyzed and studied, the expression of stress and displacement in the reinforced earth were educed, the law of stress and displacement distributing were gained based on the graph, then the theoretic foundation of designing the beam space between was laid.3.The strain in the earth was surveillanced through field test, the reliability of the law of the prestressing anchor rope beam's mechanics distributing was verified successfully by analyzing the inspected result and the theoretics calculated value.4. Through the analysis of the characteristic of the prestressing anchor rope beam's stress distributing by using the numerical simulatio software ANSYS, the reliability of the law of the prestressing anchor rope beam's mechanics distributing was verified successfully.5. Using the conclusion of theoretical analysis the orthodox method of internal force calculation and the method of designing beam space between was modified, a new and more reasonable method about designing the structure of beam and the beam space between was put forward.
