浸水高填方路堤变形性状模型实验研究

通过室内模型实验对高填方路堤在浸水情况下的变形特性进行研究,探讨了水位高低、路堤高度、加筋、填料性质等因素对浸水高填方路堤侧向变形和竖向变形的影响.实验结果表明:高水位时路堤的侧向位移和竖向位移比低水位时显著;浸水高填方路堤的最大侧向位移一般发生在填土层高度的25%~35%处;加筋能有效地减小浸水高填方路堤的侧向位移和竖向位移,起到防止路堤填土层底部开裂和提高路堤稳定性的目的.

An investigation of model test of deformation on high fills embankment soaked in water

The investigation results of model test of deformation on high fills embankment soaked in water are presented in this paper. Several factors, such as water level, height of embankment, reinforcement, property of filling, have an important effect on cross-range displacement and vertical displacement of high fills embankment. The following are some results of the test . In high water level the cross-range displacement and vertical displacement of the embankment are more remarkable than that in low level. The maximum of the cross-range displacement is located in 25% to 35% of the height of the fill soil layer. Reinforcement is able to not only reduce the numerical number of the cross-range displacement and vertical displacement, but also prevent the embankment from cracking across the bottom of the fill soil layer and improve the stability of the high fills embankment.
