The Study On Computing Method And Application In Project Of Multi-Row Anti-Slide Piles

Landslide is one of the most popular styles of nature disasters. The main cause of slopes failure is human activity including sloping, building dams or embankments, excavating of underground work and sluicing in reservoirs. Thus, many scholars focus reaearch on slopes. After many years engineering practising and theories researching, great achievement has been accomplished in slope prevention and cure, especially, the apliction of anti-slide structure developed sharply, Anti-slide pile as one main of anti-slide structure is widely applied so as to improve stability of slope. However, the designing and computing theory of anti-slide pile is not perfect.First and foremost, the interrelation of anti-slide pile and soil body is analysed and studied through Soil Arching principle. Definition and computing of soil arching are discussed baseing on modeling and method of soil arching among piles and behind piles,and optimal distance of piles and the distribution of load between front and behind of dual row anti-slide piles are worked out.Then, mechanics model of multi-row anti-slide pile is analysed according to the former analyze,and computing method about coefficient of anti-force in the door type anti-slide pile is discussed, where door type anti-slide pile is considered to be a rigid beam with the introduction of displacement equilibrium ,computing programme of matlab is applied to achieve the goal including moment, shearing force and angle, Moment,shearing force and angle of h type anti-slide pile are determined adopting analyse the state of force by ANSYS. They are utilized as a foundation to design of anti-slide structure.Finally, the main conclusion of the thesis is reached and certified through practical project of si-fang slide slope...
