The Analysis Of Predict Bearing Capacity Of Pile On The Digitization System Of Hangzhou Geotechnical Engineering(Virtual Site)

It will be in a new era that urban high-rising buildings prosperously develop in our country. Then the piling foundation engineering also comes in a busy period. However, in actual project, it brought a lot difficult to designing work that the space of under ground is so complicated, the cost of piling engineering is so expensive, the static test of long pile is so hard, and the geotechnical reconnaissance datum required is so much. The achievements of this thesis are the integrative design of predict bearing capacity of pile based on the digitization system of Hangzhou geotechnical engineering. It can predict some soil parameters, and then by using these parameters and elevation, simulate the relation curve between load and settlement of the pile, which was get from the static test of pile before. So the achievements can solve the above problems.Computer Technology, Theory and Experiment are becoming the three mainstays of every subject nowadays. Theory is the basic guide of subject development. Experiments, in particular the repetitive ones, are the fundamental validation of whether the theory is correct or not. Computer Technology makes it the most efficient that theory being involved in application. The digitization system of geotechnical engineering not only offers plenty of information, but also makes it possible to seek and analyze the datum required in great information according to the specific setting up. The datum required with synthetically optimization and analysis would be datum bases of some geotechnical engineering design. So it brings tremendous convenience to geotechnical engineering design that integrating geotechnical engineering module into this platform, which directly transmits datum bases on the virtual situ to geotechnical engineering design module, automatically and interactively solving the design work. It is the way of this thesis.The digitization system of Hangzhou geotechnical engineering developed by Protection and disaster proof institute in Zhejiang University of Technology is gotten perfect, making use of the powerful ability of datum collection, management, space query and analysis, which improves the poor situation of datum management because of complex content and form diversification. GIS, with powerful ability of visualized manipulation, also provides a visualized manipulation stage for geotechnical reconnaissance. About the physical index digitalization, on the basis of the basic theories of geo-statistics and interrelated distance and lots of groups datum of Hangzhou engineering field, the representative stratum physical mechanical index are statistically calculated. It is introduced that the common functions of GIS and the theory of geographical statistics and the algorithm theory of the computer geometric figure used for the realization of these functions. Using the Stratigraphy information, get the parameters of load transfer function. Finally, by the revised load transfer function and Visual Basic, simulate the relation curve between load and settlement of the pile, then get the ultimate bearing capacity of pile based on double curve methods.
