影响上游法尾矿坝渗流场的诸因素分析

影响上游法尾矿坝安全的各种因素中,渗流场是极为重要的因素之一。决定渗流场的因素很多,本文通过有限元数值计算,选用正交优选法综合分析了诸因素对渗流场的影响程度,并找出了主次排列顺序。同时,采用黄金分割法,探讨了初期坝的相对经济高度。文中还讨论了尾矿坝干滩长度和初期坝透水性能对渗流场的特殊影响。

Analysis of Factors Affecting Seepage Field of Upstream Method-Tailing Dam

Among the factors affecting the safety of upstream method-tailing dam the seepage field is one of the most important.There are many factors by which the seepage field is decided.In this paper through the numerical calculation with FEM,and perpendicularing optimum seeking method,the de- gree of influence of these factors on seepage field is anayzed,and their primary and secondany ar- rangement sequance is found out.The authors also discuss the relatively economical height of the ini- tial dam with the 0.618 method and the influence of the dry length and the seepage property of the ini- tial dam on the seepage field.
