| Slope engineering relates to all aspects of national economic construction , such as railroad, high way ,the open air mining engineering, construction engineering water conservancy and civil construction. On one hand it determines the safety and in gear use of all constructions which it support ,on the other hand it influences the cost of the building. With the quick increasing of population and excess exploitation of land resource, slope problem has been one of the three biggest geological disasters and the other two are earthquake and volcano.FEM takes the stress-strain property of rock and soil into account. It can dynamicly imitate the failure procession of slope and slope surface. The stress value and deformation value of every point inside the rock and soil. FEM overcomes most of shortings of limited-equilibrium method. The slope stability safety factor is caculated by strength reduction FEM. At the same time the most dangerous slip surface is presented according to the plastic zone graph.Analyzes the sensitivities of factor influencing slope stability, and the sensible factors influence slope stability are determined. The result show that the cohesion of the soil, the density and the internal friction angle are the most sensitive factors to the slope stability, the slope angle and the slope height are taken second place ,which provide some references to the reasonably and effectively design of the actual slope work.Anti-sliding pile is used extensively in the measures of land slide treatment in engineering measure. Many assumptions that the traditional theories adopted all avoided the overall analysis of the pile-soil interaction in the different degree. They take the landslide body and the anti-slide pile into account respectively and have no problem that resolves the pile-soil interaction's mechanics mechanism thoroughly. In this paper a new internal forces analysis method of anti-sliding pile is put forward. It can take the land slide body and the anti-slide pile into account as a whole,also it can consider exactly the interaction between the landslide and the anti-sliding pile, anasysed the effect of slope stability regarded to location of anti-sliding piles ,strength parameter and piles flexural rigidity is examined.Finally ,make use of the method of anti-sliding piles reinforced slope ,the project is computed and reinforced according to the FEM strength reduction.The defection bending moment and shear force of anti-sliding piles is solved ,... |
