Abstract The Datong region of China suffers from severe ground fissure (GF) disasters. Jichechang (JGF) is typical among the GFs in and most active. To provide scientific guidance for disaster mitigation, understanding mechanisms governing GF activity needs to be improved. Here, long-term monitoring data (> 10 years) JGF are used study characteristics its activity. results show that formatio...
During blasting construction in tunnel engineering, an inclined fissure near the blast hole produces “Z” type of over-excavation and subsequently affects overall effect stability tunnel. In this work, dynamic caustics testing was used to study burst propagation mode penetration form explosive cracks at different positions between holes under double-hole conditions. Results showed that existence...
