基础设施,如公路和铁路以及城市化地区,处于山坡地带,经常会受到落石的威胁,因此需要避免其受到冲击影响。在众多可行的防治措施中,地面强化路堤可认为是一种可行的技术。本文提出一套用土工格栅强化的地面路堤足尺实验并进行讨论。实验在一个专门设计和建造的测试设备上进行,用重9 000 kg的混凝土块以约30m/s的速度扔向用土工格栅加固的地面路堤上,用不同土工格栅、不同砂和不同结构设计的几个路堤在不同冲击能下进了实验,可据此定量评估这些结构的耐冲击性能。实验结果与那些从一个动态有限元数值模型中得到的结论相比,具有较好的一致性。 Infrastructure, such as roads and railways, and urbanized areas, are on hillsides and are often threatened with rockfall, so they need to be protected from shocks. Among many feasible control measures, ground-enhanced embankments can be considered as a viable technology. In this paper, a set of geotechnical tests on ground embankment reinforced with geogrids are presented and discussed. The experiment was carried out on a specially designed and constructed test rig with concrete blocks weighing 9 000 kg and thrown at about 30 m / s onto geogrid-reinforced ground embankments using different geogrids, different sand and different Several embankments of structural design were tested under different impacts so that the impact resistance of these structures can be quantitatively assessed. The experimental results are in good agreement with those obtained from a dynamic finite element numerical model.
