Swedish Circle Method Swedish circle method for analyzing the slope stability: This method was first introduced by Fellenius (1926) for the analysis of slope stability of C-φ soil. In this method, the soil mass above the assumed slip circle is divided into a number of vertical slices of equal width. The forces between the slices … Continue reading Swedish Circle Method For Analyzing The Slope Stability

Differences Between Open Caissons and Pneumatic Caissons Differences between well or open caissons and pneumatic caissons are as follows: 1. Structure ➤ Open caissons are box-type structures having their top and bottom open. ➤ Pneumatic caisson consists of an enclosure open at the bottom and closed at the top. 2. Cost ➤ Open caissons are … Continue reading Differences Between Open Caissons and Pneumatic Caissons
