Abstract: This paper discusses the main research content and technology road of the assessment system of stone deterioration in stone monuments and theirs theories of the monitoring and early-warning from the research content of assessment system of stone deterioration, the research content of the monitoring and early-warning and the research feasibility of the theory of the monitoring and early-warning of stone deterioration. At the same time, this study is also an interdisciplinary research direction, which will become a new discipline growth point of engineering geology.
