摘要
通过大量的现场调查和室内分析测试研究发现,遗存在我国西北干旱地区的古代土遗址存在的主要病害形式是墙基凹进、墙面呈蜂窝状或片状剥离、墙体开裂坍塌等。这些病害的形成是风蚀、雨蚀和易溶盐反复的溶解结晶等综合作用的结果。研究结果可为这一地区的土遗址保护提供指南。
After a lot of site investigations,analyses and tests in the laboratory,it is found that the earthen ruin sites now existing in the arid regions of northwestern China have multi-diseases,which mainly take the forms of the backoff of wall bases,holes or cancellations,scaling off,cracks and collapses. All these diseases mentioned above are caused by wind erosion,rainfall erosion and repeated eutectic salt dissolving. This finding will play an important part in guiding us to protect the earthen sites in the areas concerned.
