Analysis for Microseismic Energy of Immediate Rockbursts in Deep Tunnels with Different Excavation Methods
Publisher: American Society of Civil Engineers
Abstract: This study integrates microseismic data and data from hundreds of rockbursts of different intensities that occurred in a water drainage tunnel and four deep headrace tunnels at Jinping II Hydropower Station in Sichuan ...
Spatial Fractal Structure of Microseismic Events for Different Types of Rockburst in Deeply Buried Tunnels
Publisher: ASCE
Abstract: Based on a large amount of real-time microseismic monitoring data and hundreds of rockburst cases of different types stemming from the construction of deep tunnels at Jinping Mountain Hydropower Station, Sichuan Province, ...
Characteristics of Microseismicity during Breakthrough in Deep Tunnels: Case Study of Jinping-II Hydropower Station in China
Publisher: ASCE
Abstract: Rockbursts are a common form of disaster that occur during the construction of deep tunnels in hard rock. This is especially the case in the breakthrough stage of excavation, when even more attention should be paid to the ...
