Ancient Underground Opening and Preservation contains 59 papers presented at the International Symposium on Scientific Problems and Long-term Preservation of Largescale Ancient Underground Engineering (Longyou, China, 23-26 October 2015). The contributions focus on scientific and technical issues related to long-term preservation of large-scale ancient underground engineering around the world. The following topics are included in this volume:
1. Scientific issues facing the Longyou Grottoes
2. Weathering prevention and long-term protection strategies for the Longyou Grottoes and other large-scale underground historic sitee
3. Analysis of geological conditions and mechanisms of deformation and damage in surrounding rock in large-scale underground historic sites
4. Analysis of stability and strengthening treatments for large-scale underground historic sites
5. Safety monitoring methods and techniques for large-scale underground historic sites
6. Knowledge learned from large-scale underground historic sites that can be applied to modern underground developments.
Ancient Underground Opening and Preservation covers comprehensive papers on the research and technical progress for long-term preservation of ancient underground engineering and historic sites, and will be of interest to scientists,
engineers, business managers and government officers involved in the preservation of ancient underground openings.
