土锚设计(二)

2.2 土坡稳定分析圆弧法2.2.1 基本原理根据土坡极限平衡稳定进行计算。自然界均质土坡失去稳定,滑动面呈曲面,如图5所示。通常滑动曲面接近圆弧,可采用圆弧计算,称为圆弧法。圆弧法最初是由瑞典科学家研究出来的。位于北欧斯堪的纳维亚半岛东半部,呈南北向狭长地形的瑞典,存在大面积冰川时期和冰川后期沉积的厚层高灵敏度粘土。在修建房屋、铁路时扰动土的结构降低了土的强度。

2.2 Soil slope Stability Analysis Circular Arc Method 2.2.1 Basic Principles The calculation is based on the ultimate equilibrium stability of soil slope. The natural homogeneous soil slope loses stability, and the sliding surface is curved, as shown in Figure 5. Usually the sliding surface is close to the arc, which can be calculated by the arc, called the arc method. The arc method was first developed by Swedish scientists. Sweden, which is located in the eastern half of Scandinavia and has a narrow north-south terrain, has a large area of thick, high-sensitivity clay deposited during the glacial period and the post-glacial period. Disturbing the structure of soil during the construction of houses and railways reduces the strength of soil.
