Preliminary study on technical specification system of karst cave survey

There is no technical specification for karst cave survey in China at present. Based on the current situation of karst cave survey development, this paper studies the necessity and significance to construct a technical specification system for karst cave survey, and emphasizes its principles and thoughts. In light of system construction experience in other geological fields, the paper attempts to put forward the basic frame structure of the technical specification system for karst cave survey by means of hierarchical division, analyzes the key nodes of the system construction, and emphasizes that the specifications of cave measuring and database construction being the most important works in recent years. The specification system is the foundation of building the concrete specifications for various work contents in karst cave survey and has a great significance in developing the level of scientific research on karst cave and realizing higher social and economic value.
