泥石流在流经卡口段沟道时常出现暂时堵塞现象,并伴随着流量放大效应。文章通过典型卡口段泥石流野外调查和室内水槽试验,研究卡口段泥石流堵塞效应的影响因素与成因机制。研究显示:卡口段泥石流堵塞效应引起的流量放大或因松散固体物... 泥石流在流经卡口段沟道时常出现暂时堵塞现象,并伴随着流量放大效应。文章通过典型卡口段泥石流野外调查和室内水槽试验,研究卡口段泥石流堵塞效应的影响因素与成因机制。研究显示:卡口段泥石流堵塞效应引起的流量放大或因松散固体物源堆积而产生的流量衰减,均与卡口部位的几何条件、泥石流流体、沟域特征、是否存在附加松散物源有关。单纯卡口的存在多为泥石流流量衰减的正面因素,而是否有松散物源的加入则是卡口段泥石流的堵塞效应发生的关键因素。此研究对认识泥石流在微地貌突变动、堆积规律,完善泥石流防治技术规程方面都具有重要的理论意义和应用前景。 展开更多

On April 25,2015,a M_S8. 1 earthquake occurred in Nepal. In the Tibet area of China,this earthquake caused heavy casualties and damage to housing,roads,communications,other lifeline engineering, water conservancy and other infrastructure. This paper introduces the basic situation of the earthquake,and based on the investigation and assessment of seismic intensity,the damage of the disaster area is analyzed,and building types and damage to the lifeline systems and various industries are given. Through the analysis of the characteristics of the earthquake disaster,this paper points out the existing problems in seismic fortification,and finally puts forward proposals for the prevention and control of earthquake geological disasters, scientific planning for the restoration and reconstruction,strengthening earthquake prevention and disaster reduction propaganda,improving the awareness of earthquake preparedness in the agricultural and pastoral areas,strengthening the guidance and supervision of housing construction in rural areas to reduce the casualties and losses,and promoting the harmonious development of economy in Tibet. 展开更多
