摘要：潮濕環境土遺址的加固保護是國內外公認的技術難題。本論文結合杭州良渚文化（3300B.C.-2100B.C.）遺址群的保護開展從多方面研究。首先，通過文獻查找對土遺址的病害類型，破壞機理，保護方法和保護材料進行了簡單的了解。其次，以良渚塘山遺址為考察對象，進行了土壤含水率的測定的實驗和擊實實驗。然后，研制一種適合于潮濕環境土遺址加固保護的鈣基液態水硬性無機加固材料。通過室內試驗，用強度，滲透性和抗水解性來表征該材料的效果。

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.
