摘　　要：格宾石笼作为一种新型防护结构,具有透水性好、耐腐蚀、柔韧性好、整体性好等优点。本文在玉树地震灾区尼隆库泥石流治理工程中,首次将格宾石笼修筑为拦挡坝用于拦蓄泥石流固体物质。结果表明:与之前的防治结构相比,由于格宾馆石笼拦挡坝为柔性结构,它可以承受较大的变形而不发生破坏,较适合在地震地区使用;且防治效果良好,已经受了一次泥石流的考验,并具有较高的经济效益,可以在地震灾区泥石流治理工程中加以推广使用。Gabion stone cage is a new protective structure and it has the advantages of good permeability, being corrosion resistant, sound integrity and so on. In the regulation project of Nilongku debris flow in Yushu seismic disaster area,the gabion is firstly built as the dam to impound the solid materials. The regu- lation results show that it can withstand large deformation without damage to its structure in comparison with the control structures used before, such as grouted rubble and concrete gravity dam. It is concluded that the gabion dam is more suitable in seismic areas, for its control effect is good and its cost is relatively low, so it can be generalized in the regulation projects of debris flow in seismic disaster areas in future.
