Damage to underground structures caused by liquefaction is one of the important types hazards in field geotechnical engineering. Utility tunnels are lifeline projects cities. To ensure sustainable and safe operation utility over a design life 100 years, this paper investigates seismic response pattern liquefied site. In paper, shaking table tests were carried out on tunnel layered liquefiable B...

Under the impact of earthquake, even if slopes do not fail, integrity rock slope structure would be damaged subjected to seismic motion. The process damage, destruction and failure for is characterized by dynamic evolution stability. In areas with active tectonic activities, frequent earthquakes have a significant effect on attenuation To investigate under earthquake motions, series shaking tab...

Shaking table tests on the 1/4th-scale three-story reinforced concrete frames were carried out to investigate the effects of bidirectional earthquake motions on overall nonlinear response of reinforced concrete frame buildings. Two identical models were constructed and one was subjected to bidirectional horizontal earthquake motions and the other was subjected to unidirectional one. A series of...

An expert system, for fault diagnosis of shaking table operations, is presented. The system is designed as one element of an integrated, computer-based method for plant enhancement, for application in the mineral processing industry. The relationship between expert and conventional software techniques is discussed. The system is based on prod uc tion rule s and has been wri tten in the PROLOGla...
