Study On The Application Of Anti-slide Pier In Landslide

In recent years, landslides and other disasters happened more frequently, it is a naturaldisaster and also one of the main threats of the mountain road. Massive landslides can damagethe subgrade, destroy bridges, clog the river, and become a threat to road construction andsafe operation. Our predecessors have carried out in-depth research on the prevention oflandslide, and summed up a variety of control measures, to some extent reduce the threat oflandslides on the destruction of mankind’s engineering and life. However, due to variouslimitations, the existing governance measures may have achieved safe and reliable, but notnecessarily adapt to the engineering and economic rationality. Baihe County, Ankang City,LiuJiapo Village landslide, this paper is that in this instance, the landslide is in the west sideof State Road316, and on the east side of State Road, the Han River, so the downward forceof the landslides is relatively large, and in which the terrain is relatively steep, that causedifficulties in road construction, if the conventional control measures have been taken, notonly the cost is relatively high, but also hard to solve engineering problems. So to solve thisproblem, I daringly proposed the anti-slide pier design concept, apply it to the landslidecontrol design practice, and then the landslide stability against sliding problem will be solved.Meanwhile it combine the anti-slide and engineering together to save the project investment,and provide the experience for similar projects.In this paper, LiuJiapo Village landslide has been set as the engineering researchbackground, carried out the following research:1. According to the survey and exploration data, discussed in detail the geologicalbackground of LiuJiapo Village landslides and landslide characteristics, the stability of thelandslide is evaluated;2. on the basis of a variety of anti-slide demonstration program, combined with thespecific conditions and engineering practice, the anti-slide pier design concept andengineering program has been proposed, and its essence is the anti-slide pier will disperse asudden increase in the landslide material, landslide mass slide down between the skid pier, butdoes not affect the stability of the anti-slide pier and the use of the bridge above, meanwhilesave money; 3. There are two types of anti-slide pier in accordance with the thickness of the landslidemass, analyzed and demonstrated the effect of the two anti-slide piers, and make comparisonsbetween the anti-slide pier and anti-slide pile concerned with structure and investment, decideto use anti-slide pier control the landslide comprehensively;4. In order to verify the safety and effectiveness of anti-slide pier, used MIDAS finiteelement software to numerical simulation, analyzed the anti-slide pier stress-strain law andverified the feasibility of the anti-slide pier, on the basis of these, optimized design, to achievethe safe and economic effect.Anti-slide pier is a new idea in the landslide control, although not perfect, but has somereference value to the landslide control study later.
