庙儿沟为白龙江中游右岸河段的一条沟谷,历史上曾发生多次泥石流。在查明泥石流形成条件的基础上,分析了庙儿沟泥石流的运动特征,包括泥石流的流速、流量、冲击力。这一结论为评价该泥石流对该地区居民的生命安全及财产的影响具有现实意义。建议右岸前期施工场地和右岸上游备料场沿江设置挡墙,且场地要注意少占行洪断面,防止泥石流沉积淤塞河道。 Temple child ditch Bailong River right bank of a valley, history, there have been many debris flows. On the basis of ascertaining the formation conditions of debris flow, the movement characteristics of debris flow in Miaole Gully were analyzed, including the flow velocity, flow rate and impact force of debris flow. This conclusion is of practical significance in assessing the impact of the debris flow on the lives and property of residents in the area. It is suggested to set up retaining walls along the river at the pre-right-side construction site and the upstream stockyard on the right bank, and the site should pay attention to less flood cross-section to prevent debris flow and silting up the river.
