Processing technology for dissolving caverns breach of Yesanguan Tunnel

Sun Guoqing,Gao Guangyi,Xiao Shengneng

Strategic Study of CAE 2009, Volume 11, Issue 12, Pages 77-81

Abstract:

Taking collapse treatment of cavity rich-water of the Yesanguan Tunnel for example, the construction processes to treat collapse with the method of grouting solid in the condition of drainage and pressure decreasing were introduced. The machinery and equipment of drilling grouting as well as control measures of grouting process in the boundary conditions were also discussed, with a view to provide a reference for dealing with issues of similar projects.

A hypothesis for crack free interior surfaces of Longyou caverns caved in argillaceous siltstone 2000

Zhong Qi YUE, Shaopeng FAN, Zhifa YANG, Lihui LI, Luqing ZHANG, Zhongjian ZHANG,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 2, Pages 165-177 doi: 10.1007/s11709-010-0018-1

Abstract: Five complete caverns were discovered in Longyou in 1992.Consequently, the rock interior surfaces could be free of old cracks when the water was pumped out of the caverns

Basic Principles for Design and Construction of Underground Water-sealed Hydrocarbon-storage Rock Caverns

Wang Mengshu,Yang Huijun

Strategic Study of CAE 2008, Volume 10, Issue 4, Pages 11-16

Abstract: large amounts of hydrocarbons in China, it is of great necessity to build more hydrocarbon-storage cavernsone of the best choices to store hydrocarbons in underground water-sealed hydrocarbon-storage rock cavernsThe sealing principle, types and advantages of underground watersealed hydrocarbon-storage rock cavernsare presented in the paper and the location selection, design and construction of hydrocarbon-storage cavernsdesign and construction principles and standards of underground water-sealed hydrocarbon-storage rock caverns
