Study On Engineering Application Of Double-row Anti-slide Piles In The Reservoir Highway Landslide

Baoshan city of Yunnan province is located in southwest China,a large undulating terrain.In order to socio-economic,power generation,flood control,irrigation and other factors demand,the local government built a large number of artificial reservoirs.Slope around the reservoir subjected to the action of these long-term immersion and hydro reservoir water disturbance,etc.,can easily form a bank landslide.Local bank landslide sliding surface is characterized by steep,landslide majority fell a larger force,set up a general single-row cantilever piles not provide adequate skid resistance barrier which continued to decline.In this paper,consider using a larger stabilizing force in the multi-row anti-slide pile landslide governance.In this paper,a shoreline road landslide in Yunnan Province as the research object,by landslide reinforced with piles Governance pile spacing and selection row spacing studies selected,the following conclusions:(1)On the basis of the results of the calculation formula for BengMiao Lake landslide applicability analyzed and used to calculate the results of Yunnan mussels vague Lake Landslide of them.(2)Double pile row spacing directly affects the size of the cross-sectional size and stabilizing piles against sliding effect of stabilizing piles of paper against the first row of the slide pile spacing was assumed,on the basis of the assumption that results in the row spacing best cross-section based on the pile.In determining the size of the pile cross section,but also get the best row spacing.(3)For the remote Yunnan BengMiao Lake landslide stability analysis,using Lizheng geotechnical design software for landslide set single-row pile,analyze Anchor Pile after pile skid calculated moment,shear and displacement.Then Midas / GTS finite element analysis software to analyze the landslide from the general set of circumstances double pile,h-type anti-slide pile and so Analysis of Pile shear,moment and displacement,to analyze landslide set skid stability of the state after the pile.Finally,also set single-row anti-slide pile pile skid-row result set results are compared to the clear advantage of sliding piles at the governance Landslide determine the best program to retaining structures antiskid.
