High And Steep Slope Retaining Structures In The High Intensity Earthquake Zone

More and more people pay attention to the damage of slope retaining structures which is caused by erthquake, particularly in the earthquake in Wenchuan,landslides blocked traffic and seriously hindered the rescue efforts after the earthquake. Survey after the earthquake in Wenchuan showed that, in the retaining structures, little stabilizing piles were overall damaged, and there were only extraversion and reverse damages of the stabilizing pile.But how to play the stabilizing piles'ability to resist earthquake and how to research the weaknesses of stabilizing piles under earthquake are still immature.In this paper the summary of worldwide typical earthquake damage of the structure to resist the thrust of the landslide is briefly described, the characteristics and classification of earthquake damage are summarizesed, the characteristics of dynamic calculation is discussesed,the soil parameters of slope , changes in stabilizing pile'design parameters and different anchored force influencing on stabilizing pile resisting earthquake is researched, earthquake's mechanism of action of stabilizing pile is described,the construction points of stabilizing pile and anchor stabilizing pile are described too.Based on the data of the stabilizing pile which is situated the railway line from Chong-Qing to Li-Chuan, ANSYS compute software is used to study the stabilizing pile's seismic response and engineering characteristics whith different soil parameters and design parameters.The analysis and summary are summarized as following:â‘ This paper was analyzed the slope stability in both static and seismic cases, obtained slope stability safety factor ,and provided a basis for governance of the slope.â‘¡Discussing the changes in soil parameters how to affect the stabilizing pile,analyzing the angle of internal friction and cohesion on the pile of soil arching.â‘¢This paper was analyzed the pile spacing, anchor rod depth and section size to consist of stabilizing pile, seismic characteristics and the relationship between various design parameters selected.â‘£This paper, aiming at the typical parts and weak links, puted forward recommendations to strengthen measures. It may provides reference for aseismic design code for the future.
