Optimization Design And Foudation Deformation Anaalysis Of Foudation Pit Support In Qingdao

At present,with the domestic foundation toward a larger area,a greater depth of the direction of development,in order to ensure the safety of foundation pit engineering construction and people's life and property from damage,which means the safety evaluation of foundation pit are becoming more and more important,and the foundation pit safety,taking account of three important factors,one is the geotechnical prospecting accuracy;The two is the design of supporting structure is reasonable;the three is the construction quality assurance and risk response measures are timely,the current through the excavation of foundation pit deformation monitoring design and construction process is in place and information processing is timely reflected.Geotechnical investigation decision support structure design is reasonable However,the excavation process monitoring is in place and whether the information processing and timely verification and adjustment of the design of supporting structure,so whether the three complement each other and influence each other.So if a pit can depend on the safety of construction,geotechnical investigation,design of supporting structure,process monitoring is in place and the accuracy of information processing with the timeliness of excavation.At the same time,in order to meet the demand of foundation pit engineering safety,how to take into account the economy and the influence of foundation pit surrounding environment less in the selection of foundation pit supporting scheme,but also need to solve the foundation pit in the process of design.So this article focuses on the research of concrete foundation pit engineering project The analysis,summarized the domestic and foreign scholars in the investigation of geotechnical foundation engineering,geotechnical engineering evaluation and foundation pit supporting design and optimization analysisof foundation pit safety theory.And according to the actual engineering case of seismic site effects of foundation pit project,site stability and suitability,analysis and evaluation of geotechnical engineering characteristics and soil corrosion,propose the optimum design and design parameters of concrete supporting structure;And analyze and evaluate the deformation of foundation pit and its surrounding environment in the process of excavation and safety;the main contents are as follows:(1)By reading a lot of literature,summarized the domestic and foreign scholars in geotechnical investigation and geotechnical engineering evaluation of foundation pit engineering and foundation pit support design and analysis of security theory;and concludes the excavation scheme optimization principle and process;(2)The site engineering geological investigation,and according to the detailed survey results of seismic site effects of foundation pit project,site stability and suitability,evaluation and analysis of the corrosion of geotechnical engineering and geotechnical engineering properties of soil;(3)According to the geological characteristics of the soil engineering,material properties and the surrounding conditions of the foundation pit excavation combined with optimization principle and process,selection of pile anchor retaining structure as engineering supporting structure form,and combined with the characteristics of the foundation pit supporting structure parameters of section design,guarantee has been reached in the deep foundation pit slope and the safety of the surrounding environment under the premise of the foundation pit engineering more economical;(4)For the foundation pit design and construction of foundation pit projects,through the establishment of the displacement of slope excavation,supporting structure and surrounding buildings,pipelines and other monitoring methods and analysis of monitoring data,analysis and evaluation on the safety of foundation pit and its surrounding environment in the process of excavation.
