Landslide Unstability Analysis And Reinforcement Technology In Zhong Long Park

The landslide is a global geological disaster, causing casualties and huge economiclosses to many countries and regions. The slope stability analysis is a critical content in thegeotechnical field.This paper, taking Dalian Xinghai Zhong Long Park landslide as an example, on thebasis of the geological disasters detailed investigation in Dalian Xinghai area, throughcomprehensive analysis methods of combining the field drilling, indoor test and theoreticalanalysis, numerical simulation and landslide monitoring, to analyze the causes of landslides,landslide stability analysis, reinforcement effect evaluation and so on has carried on thesystem research. Firstly, analyzed geological survey datas, determined the main mechanicalparameters of rock and soil body about elastic modulus，severe, cohesion, internal frictionangle, for the study of landslide genesis, stability analysis and landslide governance providesthe reliable data. Then the SoilWorks software simulation analysis was carried out on theslope, the analysis results show that slope under the condition of rainfall in serious instability,and Zhong Long Park landslide is verified. Then aiming at the causes of landslide, proposedthe combined support system that cutting slope, improving the structure of truncated flooddrainage, using anchored reinforcement for the first level of slope and prestressed anchorcable reinforcement for the second level of slope, using reinforcing mesh and shotcrete for theslope surface. In order to prove that the treatment schemes of langslide are effective in theory,using SoilWorks software for the reinforcement of the slope stability analysis and calculation,calculated the indexes of landslide soil stress and strain and minimum safety coefficient, andresults showed that the slope meet stability requirements, reach steady state. Finally, in orderto evaluate the effect of the landslide, the cracks in the buildings, the top horizontaldisplacement, deep horizontal displacement and anchor bearing were monitored. Through theanalysis of the monitoring results, it shows that the landslide treatment scheme is correct andeffective, the slope reached the steady state and the expected control effect，getting thesuccess to the control for Landslide geological disasters. Through the study of this paper, itproved the reference for landslide control in Dalian region and the coastal cities.
