浅议预应力锚索防护要求与存在的问题

我国岩土锚固规范中对锚索耐久性的要求相对较低,且可操作性较差,结构的安全性重点放在各种强度要求上,而对环境因素(如工程周围水、土中有害化学介质侵蚀等)下的耐久性要求则考虑较少。随着我国基本建设的迅猛发展,作为土建结构重要组成部分的岩土预应力锚索工程的耐久性应引起相关研究、设计和施工部门的高度重视。

Discussion on Safeguard Requirement of Prestress Anchor Cable and Existing Problems

In china,specification of geotechnical anchorage cable requirements on durability are relatively low,and operability is poor,the structure safety focused on various strength requirements,while environmental factors(such as engineering around the water,soil hazardous erosion of chemical media,etc.) are less considered.With the rapid development of infrastructure,as an important part of civil structures,durability of rock-soil prestressed anchor cable engineering should be paid high attention for the related ...
