Abstract Research purposes: The traditional way is still adopted for treating underground water to long tunnel in karst zone. Therefore, it causes ecological environment surrounding tunnel damaged, occurrence of geological disaster and serious influence on sustainable development. This paper is written for elimination people’s misunderstanding and changing concepts.
Research methods: The demonstration is made in this paper of comparison in aspects of technical feasibility economic index and construction schedule under the same development condition of karst and underground water with taking data as basis.
Research results: The principle of “Take prevention as the dominant factor” should be kept for environmental protection. The concrete measures, construction method and caution for construction are put forward for the area for which a fully closed scheme should be adopted. The principle, primary standard and method of advanced pre-grouting are present for prevention water and drainage to long tunnel in karst zone.
Research Conclusions: The principle of full closure should be kept to long tunnel in karst zone with complex geology when geological disaster threatens the safety of construction and operation，and the worse of geological environment influences sustainable development of the area. If the scheme is correct and measures are suitable, construction will keep going on smoothly without trouble in further.
