硬度测量在土遗址保护中的应用问题

硬度试验是材料机械性能试验中最简单易行的一种试验方法。硬度值可以基本反映材料的强度特性,但它并非材料独立的基本性能,而是取决于其所采用的试验方法。各种硬度试验方法使用条件要求各异,如何根据土遗址特点,选择合适的硬度检测方法,保证检测精度是目前土遗址保护中需要解决的一个问题。本文在综合分析各种试验方法的基础上,给出了土遗址保护中硬度检测需要遵循的基本原则。

The Application of Hardness Test on Consolidation of Earthen Sites

Hardness test is one of the simplest testing methods for mechanical properties of materials. Hardness value can reflect the strength character- istics of materials, but it is dependent on testing methods that require different conditions. How to choose a suitable testing method for earthen sites and guarantee its testing preciseness is one of the biggest challenges needed to be addressed in current earthen site protection. Based on a comprehensive analysis of all kinds of hardness testing methods, the paper puts forward some basic principles needed to follow in the conservation of earthen sites.
