文档编号:CL095  文档字数:14507,页数:36

摘要：潮湿环境土遗址的加固保护是国内外公认的技术难题。本文档结合杭州良渚文化（3300B.C.-2100B.C.）遗址群的保护开展从多方面研究。首先，通过文献查找对土遗址的病害类型，破坏机理，保护方法和保护材料进行了简单的了解。其次，以良渚塘山遗址为考察对象，进行了土壤含水率的测定的实验和击实实验。然后，研制一种适合于潮湿环境土遗址加固保护的钙基液态水硬性无机加固材料。通过室内试验，用强度，渗透性和抗水解性来表征该材料的效果。

Abstract: the ruins of soil moisture environment protection are recognized and strengthening technical problems. This paper combining site of hang Zhou liangzhu culture（3300B.C.-2100B.C.） from the aspects of protection in research. First, through the literature search ruins of soil types, mechanism of disease, protect and protection of material. Secondly, the site for the liangzhu pond inspects an object of soil moisture content determination experiment and the compaction test. Then, rigid reinforcement material water. Through the laboratory test, with strength, permeability and resistance to characterize the hydrolysis of materials.

Keywords: wet environment；soil sites；Reinforcement
