Because of the special engineering nature of loess, for example: water sensitivity, large holes, structural, etc., resulting in a variety of engineering disease appeared in the building in loess area. These diseases cause great losses to life and property. In the long term of engineering practice in the loess area, many scholars and engineers who have accumulated rich engineering experience, in buildings, roads, bridges, railways, tunnels and other projects. However, the mechanism of disease for some projects and treatment measures remain unclear. In this research, through scientific and systematic study and a large number of tests, to identify the major engineering diseases and the key issues, to find the mechanism of engineering disease and find effective treatment measures.
With the frequent occurrence of earthquakes, which cause severe damage to some underground structure, the existing domestic and international aseismic norms about underground caverns become too briefly, which can not adapt to the development of underground tunnels in high intensity earthquake areas. Now, our aseismic study of expressway tunnel is in urgent need. Combining with the project of aseismic and shock absorption of tunnel in YALU expressway, this paper study the seismic dynamic response of the shallow double-hole highway tunnel. The research shows that: rock-level has important effect on seismic dynamic response of the double-hole tunnel; with the the improvement of rock strength and integrity , the seismic response of tunnel lining tends to decrease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
