摘　　要：基于极限平衡滑移线理论,采用差分算法编制了针对包头地区普遍存在的双层地基数值计算程序 由程序分析了无重土和有重土中临界深度与土内摩擦角的关系,给出了考虑土重时土体的临界深度拟合公式。On the basis of limit equilibrium slip line theory,a numerical procedure aiming at the common two-layer foundation in Baotou was developed by using difference algorithm.The relation of critical depth and inner friction angle in weightless and weight soil was obtained from the procedure,which gives fitting formula of critical depth in the weight soil and it is available by comparison.

关 键 词：双层地基 临界深度 有重土 无重土
