Study On Slope Supporting Scheme Of South Tourist Service Center In Liye Ancient City

In recent years,with the rapid development of China’s social productivity,the country’s infrastructure construction has been greatly improved.In engineering construction,the slope is one of the most common forms of engineering,and the slope instability and collapse often encountered in engineering construction is one of the three recognized geological disasters(floods,landslides,mudslides,earthquakes)that are recognized worldwide..Landslides not only threaten human life,but also cause huge losses to the national economy.With the continuous advancement of science and technology and construction equipment,the slope support technology has been constantly improved and innovated,and various types of slope support methods have been rapidly developed.This paper mainly introduces a certain section of slope in the construction of South Tourist Service Center in Liye City to carry out a detailed design introduction,and analyzes its stability through monitoring data to test whether its support scheme is reasonable.The work carried out in this paper mainly includes the following aspects:(1)Through experiments,the geotechnical and mechanical properties of the slope of the studied object are obtained.(2)The stability of the original slope was calculated and its residual sliding force was calculated.Based on the calculated stability before slope support,on the basis of in-depth knowledge and study of existing engineering geology,hydrogeological data,and surrounding environmental conditions,refer to successful design and construction experience for various scenarios.Analyze,demonstrate and optimize,and ultimately determine the slope support plan.And detailed calculation and introduction of its support structure and design.(3)Through the "Technical Specifications for Building Slope Engineering","Specifications for Design of Concrete Structures" and other specifications and rationale for geotechnical software,and then According to the sharing force of the lattice anchor and the anti-slide pile determined before,the stability of the slope and the anti-slide pile after the slope support are checked respectively.In order to verify whether the supporting design is reasonable.(4)In this project,the factors influencing the slope stability are mainly the excavation construction of the soil in front of the rainfall and anti-slide piles.In order to explore theinfluence of rainfall on the slope,this paper analyzes the monitoring data under rainfall and sunny conditions,and obtains the X coordinate direction,Y coordinate direction and Z coordinate direction under rainfall(great rainstorm)and sunny days.Daily average displacement.According to the obtained range of the daily average displacement of each coordinate under the rainfall state,the displacement of the slope can be predicted to a certain extent in the case of continuous multi-day rainfall in the future,so as to further ensure the stability of the slope.In order to prevent the instability of the slope caused by excavation and construction of the soil in front of the anti-slide pile,after the completion of the construction,the slope was measured,and the change map of the slope displacement was obtained,and it was analyzed whether this situation would affect the Slope stability has an effect.Finally,through the monitoring data from November 19,2016 to August 28,2017,the cumulative displacement variation of each coordinate was obtained,and the stability was analyzed based on the change curve and accumulated displacement variation,and further demonstrated that the The rationality of the support plan.
