如下图所示，存在点 $(x_0,\ y_0)$ 和点 $(x_1,\ y_1)$ 以及待求点的横坐标 $x$ ，则可用下式计算待求点的纵坐标 $y$ ：

$$ y=\frac{y_1-y_0}{x_1-x_0}\times(x-x_0) + y_0 $$

1. Input parameters of soft / 软件输入参数

1.1 parameters of slope shape / 坡形参数

1. Slope heigh / 坡高 $H$ (H)
2. Slope angle / 坡角 $\beta$ (beta)

1.2 Mechanical parameters / 力学参数

1. Cohesion / 黏聚力 $c$ (c)
2. Gravity / 重度 $\gamma$ (gamma)
3. Angle of internal friction / 内摩擦角 $\varphi$ (varphi)
4. Groundwater coefficient / 地下水系数 $r_{\rm u}$ (r_u)
5. Horizontal scanning interval seismic coefficient / 水平地震系数 $\alpha_{\rm w}$ (alpha_w)

2. Calculate steps / 计算步骤

2.1 Step 1 / 步骤 1

$$ f_{\rm x} = \frac {c}{\gamma H} $$

$$ f_{\rm y} = \tan \varphi $$

$$ r_{\rm u} = ? $$

$$ \alpha_{\rm w} = ? $$

Note: The $f_{\rm x}$ code in Formula (1) is written asf_x, and the $f_{\rm y}$ code in Formula (2) is written as f_y.

注：式 (1) 中的 $f_{\rm x}$ 代码写作f_x，式 (2) 中的 $f_{\rm y}$ 代码写作f_y。

The current safety factor f ('f') can be calculated by the Formulas (1), (2), (3) and (4) combined with the table.

由式 (1)、(2) 、(3) 和 (4) 再结合表和插值法可计算得当前安全系数 $f$ (f)。

2.2 Step 2 / 步骤 2

$$ H^* = \frac{c}{\gamma \tan \varphi} $$

$$ H=? $$

$$ \beta = ? $$

$$ r_{\rm u} = ? $$

$$ \alpha_{\rm w} = ? $$

The slope shape influence factor $\delta$ (delta) can be calculated by the Formulas (5), (6), (7), (8) and (9) combined with the table.

由式 (5)、(6)、(7)、(8) 和 (9) 再结合表和插值法可计算坡形影响因子 $\delta$ (delta)。

2.3 Step 3 / 步骤 3

$$ F_{\rm S} = \delta f $$

The safety factor $F_{\rm S}$ (F_S) can be calculated from Formula (10).

由式 (10) 可以计算安全系数 $F_{\rm S}$ (F_S)。
