The Optimization Of Changchun Farmer’s Market Foundation Pit Supporting Design And Calculation Method

With the development of society and the needs of urban construction，there aremore and more issues involved in deep foundation pit supporting design. Theoptimization of foundation pit supporting, among these issues, is a problem related tothe safety, stability and economics of structure. It’s getting more attentions nowadays.The content makes the research on the choice of the optimization of foundation pitsupporting about Changchun Farmers Market, mainly by the way of calculating. Itraises the right supporting form, row pile supporting, basing on summuring the formers’results according to the character and the site condition of the engineering．It analyzes the stability and calculates the displacement and internal force of thestructures by using Lizheng software, according to the results. It then uses Midas-GTSto analyze the deformation characteristics of soils all around. It analyzes the regulationsand characters between the supporting structure and soils’ deformations arounded,according to simulating results when the row pile supporting has been excavated. It alsostudies mechanism to provide the basis on controlling the deformation happens. Itfinally raises the most economical calculating for the foundation pit supporting designof this project, considering the actual site conditions, the buildings nearby, the positionsof city pipeline, also satisfying the safety and stability of the project and buildingsarounded, then it provides references to the local area.It can choose the best designing by optimizing the foundation pit supporting, thenmake the foundation pit supporting design satisfy the requirements of not only thestability and safety，but also the economics and rationality．...
