... on an axisymmetric finite element analysis of salt caverns and its impact in casing integrity for scenarios of casing shoe set above and below salt base. With the methodology proposed for evolution of cavern dissolution, displacements and plastic equivalent strain are compared. Results show that the casing axial...

... powerhouses, transformer halls, desilting caverns and surge chambers. It is a well-known fact that the Himalayas, which is more than 3000 km long and 300 km wide, is generally characterized by steep slopes, lofty hills, and complex geological and tectonic settings. Therefore, detailed engineering geological...

... Abstract The demand for gas storage operations with high withdrawal rates and operation modes different to a seasonal storage regime requires a more detailed rock mechanical consideration of thermal induced stresses in the vicinity of the caverns. This means that the change of gas temperatures...

... Abstract A lined rock cavern (LRC) is an alternative container for compressed air energy storage (CAES) to store high-pressure air that is later used to produce electricity. A critical requirement of CAES in LRCs is that the inner seal should provide adequate sealing capacity to prevent air...

... leakage initiation and the importance of the pore pressure measurement for monitoring the gas-tightness of the LPG storage cavern based on the test results.

... Abstract Demand of high pressurized gas storage in underground rock caverns is increasing. Compressed natural gas (CNG) and compressed air energy storage (CAES) are one of the promising examples after since lined rock cavern (LRC) concept has been verified through in-situ pilot tests. Two key...

... Abstract As a powerhouse, a transformer or a valve chamber, large underground caverns are a major element of hydropower plant. On the contrary to galleries and shafts which are linear and long underground structures, large caverns are designed with often complex geometries and large spans...
