The Study Of Large-scale Aqueduct Pile-soil Interaction Model Test And Comfir The Theory Model

In the past many years, a lot of scholars have got some research results in "the ooperation function of Pile and earth" problem by theoretical analysis, the experiment and observes. With the development of the city and industry construction, the form of large-scale poles has been applied more and more. So grasping the service function of group poles and achieving rational design have the practical significance. A large amount of model experiments and reality easures on project indicate that the properties of large-scale poles foundation are obviously different from the singly one, and it is affected by the interaction of holding platform .pile and earth pole .So it is necessary to do the systematically analysis and studying.The content of this research is that the important ingredient of the Country Natural Science Fund ?the theory study of the interaction of large-scale aqueduct pole -soil driving force and the mechanism damping under the earthquake effect? (approves a number: 50479026) and Shaanxi Province department of education special fund ?the key technology problem studies of large-scale anti-knock aqueduct structure analysis? (approving a number: 04 JK232).In this research, the pole foundation adopted in the yellow U shape aqueduct is regarded as the object of the study. The key of the study is to progress the experiments about the interaction of pile and earth and the theory model verification of the interaction of large-scale aqueduct pole and soil driving force.According to now available test equipment and condition, working out the design scheme of experiments about the interaction of large-scale aqueduct pole and soil coactions tests and experiment technology studying, and put then into effect. And it show the support capability, the forced characteristic property and the deformation characteristic property under the different conditions and different rate of diameter.Finally, it handle and sum up the result of the experiments, analysis the interaction of the hold the platform , the pole and soil and compare the edge pole with angle pole according the testing data of the experiments .Finally, according to the experiments result to confirm the finite element theory model on the interaction of the pole and soil result from the earlier stage project job, reckoning and procedure Both are compatible , especially the dynamic analysis, the testing result about this aspect has not seen news report. It not only confirm the serviceability of the finite element method, but also verify the reliability of the testing scheme and the reliability of the result of the experiments. This comparation has the certain reference value to a further research of the large-scale aqueduct.
