摘要
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。
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.
