关于预应力锚索加固效应研究的几点看法
|
摘要
分析了预锚加固体系现行设计方法所依据的基本理论，认为改进设计方法的关键在于加强对加固机理和效应的认识．通过分析预锚体系的特点，对单根预应力锚索研究的重点问题以及如何提高预锚加固的效果提出了自己的观点．此外，还探讨了有限单元法在预锚计算中的应用，以及群锚体系的整体效应和计算特点．
In this paper, the basic theory applied in the current design method of reinforcing systems of prestressed anchored steel rope is analyzed, and it is suggested that the key to the improvement of the design method is to enhance the knowledge of the reinforcing mechanism and effect. After analysis of the features of prestressed anchored steel rope systems, several comments are made on what are important problems in the study of such systems and how the reinforcing effect can be improved. The problems of how to apply the finite element method to calculate such systems, and how to calculate and study a large system consisting of a group of prestressed anchored steel ropes are also discussed.
