| Abstract: | The principle of the counter-thrust technique is expounded in this paper. The method for determining the relative displacement is discussed and a simplified formula for the counter-thrust force is derived. The technical points for construction are also delineated. A case study is exemplified to justify the effectiveness of the counter-thrust technique. |
