The Ankang Ring Road Landslide Stability Analysis And Treatment Evaluation

In order to improve the economy of mountainous region, highway construction hasbecome the top priority of the highway construction in our country. Due to the nature of theterrain conditions, in the building process, the engineering slope can be seen everywhere. Inrecent years a large number of continuous rain, bring a few natural disaster, to some slope,collapse and slide scour, the influence is great, not just threat pedestrian safety on the highway,also threate slope the upper portion of the structures and buildings in the use safety of things.In the past a period of time, thousands of landslide has been treated.That has took a lot ofmaterial and financial resources.As a large number of landslide to be treated, peopledesperately want to know how is the landslide treatment effect.Therefore, if the effect oflandslide treatment has an objective evaluation, and used to guide the optimization of thesimilar landslide treatment that can bring great benefit. In this paper, to the Ankang ring roadlandslide for example, on the basis of the system research of the landslide basic features,theformation mechanism and stability,propose design scheme, and evaluate the effects oftreatment.As follows:(1)through the regional geological environment,lithlogical composition oflandslide,analysis of deformation and failture characteristics,the paper sums up the internalfactors of landslide and external conditions of the formation of landslide.(2) By using transfer coefficient method respectively, and the finite element strengthstrength reduction, consider the influence factors of landslide, points to two conditions of thelandslide stability state evaluation calculation. And through the numerical simulation andanalysis of landslide stress state, reproduce the well-being of the ring road landslide formingprocess.(3) According to the stability of landslide,the paper puts forward the design of thelandslide treatment, and by uses of finite element software Midas/GTS, numerical simulationcalculates and analyses the stress state and deformation the characteristics of after treatmentof the landslide and anti-slide pile. (4) For landslide of displacement, stress and strain state changes, and the treatment of thestability and analysis of landslide treatment effect evaluation, the conclusion that the effectsof the good governance.
