摘要
以赛日托沟泥石流及堆渣体治理工程为例,在渣体上游采用重力式溢洪坝,用于拦挡泥石流固体物质、截断沟水及形成引水入口;在渣体上通过对已有堆渣体的削坡支护措施,确保渣体边坡稳定,并在堆渣体上修筑排洪渠;在出口段通过排洪洞将沟水引至下游旗下沟,对于沟口不稳定渣体采用网格梁及系统锚索支护。该工程经过近几年运行,效果良好,可作为类似工程借鉴和参考。
In the mudflow and slag conservation project of Sairituo gully, the concrete gravity overflow dam is adopted in the upstream of the slag, used to block the mudflow solids, cut off the water and form the entrance of penstock. To ensure stability of slag slope, in the slag body, the slope cutting support measures are adopted for the slag, and build a flood relief channel on the slag. In the outlet, the drain is lead up to the downstream gully of Qixia through the adit for draining. The frame beam and system anchorage cable are used for the unsteady slag of the groove. The project has run in recent years, the result is good. It can be used as reference for similar projects.
