ANALYSIS OF THE DEEP-SEATED CONCRETE SLAB FOR SETTLEMENT CONTROL AT BRIDGE APPROACH EMBANKMENT

摘要：

The deep-seated reinforced concrete slab, which is different from the traditional reinforced concrete slab for settlement control at bridge approach embankment, can avoid the complaints about the reinforced concrete slab cracking with the long-term impact action of vehicle. A simplified two-dimensional plane strain finite element model for bridge-approach, in which soil parameters are selected from the geological prospecting data, is proposed. The comparison between field experiment and theoretical results shows the characteristics of subsidence of bridge-approach overlaying the deep-seated concrete slab. Parametric analysis is also performed to investigate the influence factors of disposal effect of the deep-seated reinforced concrete slab. The results indicate that the deep-seated concrete slab has more advantages on the settlement control and alleviating vehicle bouncing at the bridge approach.
