with a high probability. The earthquake damage of tunnel will bring great trouble to the rescue work of these areas. In recent years, some surveys of earthquake damage of building show that the tunnel... an active fault that has a dip angle of nearly 90° and a thickness of 5-9 m. 2.2 Experimental equipment A multi-functional shaking table test system of high-speed railway of Central South University......

for the high-speed train on the bridge during earthquakes. Recently, the analytical study of ZENG et al [16] confirmed that the particular position of the moving cars on the deck affects the response/safety of the vehicle significantly when an earthquake happens. However, the above studies have been conducted on high-speed railways. In fact, the running speed of heavy-haul trains is usually around......
of the choice of high stiffness of GCS or the use of less rigidity of the bridge approach embankment of LS. When two different backfill geometries for the different of the route vertical position behind......
-liquid-limit sandy silt, high-liquid-limit-silt and clayey gravel. The histograms of the optimum moisture content, moisture content and plastic limit of five soil samples were presented in Figures 5(a)-(e... were unqualified in this index. The change amplitudes in compaction degree of the high-liquid- limit silt was smaller than other four kinds of soils. The average compaction degree of all the soil samples......
high value (e.g., 0.5), the results of critical Ka of different μ tend to the same. For example, the Ka curves for μ=0.5 and 1 are overlapped in the absence of seepage effects, and even including......
deterioration, the damages of roadways, such as pavement damages, high-filling embracement damages, deep-cutting slope failures, etc, are difficult to avoid [8, 9]. To decrease the possibility... of a pillar [20, 21]. However, some pillars with high safety factor usually fail unexpected, resulting in cascading pillar collapse. That is because the failure of any pillar must disturb the adjacent......
