土坡稳定计算是工程中经常遇到的问题。在工程实践中,至今广泛采用的计算方法,仍然是瑞典园弧条分法。这种方法概念明确,便于分析各种情况下的土坡稳定性,而且它已为工程实践所验证,在计算成果上是可靠的。但在分析每一滑动面时,所需的计算工作量仍然甚大,繁琐费时。然而,对于这种繁琐的计算是可以改进的,它可以代之以简便的图解方法。本文试图在条分法的基础上,提出一个简便的直线图解法。即通过两组典型特性线F_1(α)～f_1(h,α),F_2(α)～f_2(h,α)以及A～f(k_1,φ),B～f(k__2,c),并借助于两个转换系数k_1和 Stabilization of soil slopes is a common problem in engineering. In engineering practice, the widely used calculation method so far is still the Swedish Arc Curves. The concept of this method is clear, and it is easy to analyze the stability of soil slopes in various situations. It has been verified by engineering practice and is reliable in the calculation results. However, the computational effort required to analyze each sliding surface is still large and cumbersome. However, this cumbersome calculation can be improved, it can be replaced by a simple graphical method. This article tries to propose a simple straight-line graphic method based on the stripe method. That is to say, through the two typical characteristic lines F_1 (α) ~ f_1 (h, α), F_2 (α) ~ f_2 (h, α) and A ~ f (k_1, φ) With the help of two conversion coefficients k_1 and
