【摘要】 两岔沟泥石流为一大型潜在危险性泥石流,由于地震和人为等因素的影响,泥石流发生的可能性较大.在现场踏勘和分析两岔沟泥石流流域分区特征的基础上,从形成泥石流的地形、水源、物源等主要方面着手研究.通过经验公式估算及实测计算相结合的多种分析方法,来综合评定泥石流的流体重度、流量、流速及一次泥石流流过总量.一方面,验证了经验公式的适应性,另一方面,揭示了泥石流的发展趋势,为后续的防护和治理提供了可靠的基本物理力学参数.更多还原

【Abstract】 The Liangcha Gou Debris flow is a large debris flow with potential hazard. Due to the effect of earthquake and artificial factors,the debris flow is very easy to occur. Based on survey and analysis on partition characteristics of the Liangcha Gou debris flow,the terrain,water,material sources and other major aspects of forming debris flow are analyzed. By combining the empirical formula estimation and the actual calculation,this paper comprehensively evaluates the fluid density,flow,velocity,and the total flow of debris flow. On the one hand,this paper validates the adaptability of empirical formula; on the other hand,it reveals the development trend of debris flow,and also provides the reliable basic physical and mechanical parameters for subsequent protection and treatment.更多还原
