Abstract


In these years, with the rapid development of China’s urbanization, each city top (or even super-tall) building planning is often seen in press. To the high development and the development of underground space, is to save the limited land resources, adjust land use structure, civil air defense and national defense construction of the inevitable choice. Therefore, brought the foundation pit engineering growth spurt. However, in the foundation pit engineering in exist:theory behind the practice and theory is unable to correctly reflect the actual construction process problems. So, in deep foundation pit engineering construction process, carry on the omni-directional security monitoring, accurately forecast the project risk, and the monitoring result feedback to foundation pit design, the development and research of deep foundation pit is of profound realistic significance.First of all, for deep foundation pit supporting in the design theory and calcula-tion method, etc. are reviewed. There is summarized research deficiency:the disconnection between theory and practice, field test results, the conventional method can’t less precise.Secondly, for deep foundation pit monitoring system monitoring project selection, monitoring methods and monitoring equipment, the selection of monitoring points of the design and production, the application of the monitoring and predicting value analysis. Appeared in the process of monitoring the actual problem puts forward the prevention and solution.Again, to pile anchor supporting system of deep foundation pit engineering as an example. From the soil pressure, pile body internal force, pile body deformation, the bolt pretension stress and so on four aspects of monitoring. Monitoring results obtained, and analyzes its reason. To test the rationality of the theoretical design calculation method and the accuracy of numerical simulation provides a reference for the.After that, by using finite element software MIDAS/GTS carries out the engineering numerical simulation research. Focusing on the supporting pile body deformation with time (construction process) change regularity of distribution has conducted the analysis research.Finally, get some benefit similar foundation pit design research results, for the safety of the foundation pit supporting project and the design and construction of the economy have provided the certain basis.
