Monitoring And Analysis Of The Stability Of Artificially Piled Mountains

How to cure the urban diseases which were left in the process of urban expansion has become a difficult problem in the process of sustainable urban development.From those successful cases in city construction,piled mountain scenery can be important engineering measures to solve these two problems at the same time,the integration of multiple beneficial projects explains the profound connotation of sustainable urban development from the perspective of economic,environmental and social benefits,achieved sustainability at the planning and strategic levels.Due to the the difference in mechanical properties between the original rock,soil and the materials which were used to make mountain,sudden change in properties at the interface happened,which makes the problem of artificial filling mountain soft zone prominent,mountain stability greatly limits the mountain height and scale.To solve the problem of related engineering problems of stability,this paper takes the egg hill abandoned mountain filling and ecological restoration project?flling materials mainly come from the large amount of engineering spoil and construction waste which were generated from the construction of the stadium in Zhenjiang?as an example,makes the comprehensive introduction of basic performance experiments,the construction control in the process of filling the mountain,settlement deformation monitoring,the finite element simulation and settlement prediction.The main research contents are:1)Through different soil mechanical tests,this paper obtains the mechanical performance data of the flled mountain soil;2)Set up various professional monitoring equipment on the ground to monitor the displacement and settlement of the mountain.Finally,the monitoring data of each time period is summarized,summarizing the deformation law of the mountain through monitoring data;3)Establish a mountain model with FLAC^3D simulation software to simulate the mountain deformation process.Finding a more effective way to evaluate the stability of the mountain through simulation data.It is found that the stability of mountain masses can be analyzed more comprehensively in combination with the change trend of SH/S;4)Perform fitting calculations on 10 sets of time and settlement data to obtain a more accurate fitting curve suitable for predicting settlement,which can be used to predict future mountain settlements.This article finally obtained systematic research results through more field tests and construction monitoring data,combined with calculation simulation analysis,hoping to provide demonstration and guidance for the further development of other mountain pile projects in the future.
