Analysis And Research Of Anti-slide Pile In The Rock Landside

With the development of national economy, the construction of railways, roads, mining, water conservancy and civil engineering often plays a detrimental role effect on the environment, and resulting in landslides. Therefore the study of slope stability is very important. A variety of landslide control program is to be used, due to the location flexible, the construction affected on landslide are limited, simple in construction, security and many other advantages, so anti-slide pile are widely used in slope stability of governance. In this paper, through theoretical study, experiments and numerical simulation to analyze anti-slide pile design and rock slope stability. The main contents of this article include the following:â‘ Introduce the types of slope and factors that affect the slope stability and the step of piles design. In addition, according to the different nature of the rock to assume the distribution landslide thrust on anti-slide pile. At the same time introduced the method of determine flexible and rigid piles and method of calculating internal forces.â‘¡As Xiang jia po slope for the engineering background, use transfer coefficient method to calculate the landslide thrust and stability coefficient in natural condition and rain condition. Indicating that the slope is instability under the rain condition and it need to be supported. According the landslide thrust to calculate pile's internal stress and draw the shear and moment chart.â‘¢Use the finite element software ANSYS to carry out numerical simulation of Xiang jia po slope. The results show that the horizontal displacement is small in the natural condition, and the slope in a state of stability. However, in the rain condition, the slope displacement is large, plastic zone extends to the foot of the slope, the stability coefficient is decrease. After set up anti-slide pile, the horizontal displacement is significant decrease, plastic zone extends to the middle of slope, do not reach the foot of the slope. Show that the anti-slide pile slope plays a good role in landslide control to prevent slip and enhance the slope stability.â‘£After analyzed the susceptivity of factors which effecting anti- pile strain, such as slope angle, the depth of anti- slide pile anchor, interlayer friction coefficient. Some of results are found as follow: The susceptivity of slope angle effecting anti- pile strain is the most important, the second factor is interlayer friction coefficient, and the susceptivity of the depth of anti- slide pile anchor effecting anti-slide pile strain is the limited.
