Abstract


Guanzhong loess due to special historical causes , the special nature of the works . Pile as an effective form the basis of its in the region and the engineering behavior research is undoubtedly of great significance. Drilled pile vertical bearing capacity and settlement has been the need to study the problem . Based on sound theoretical basis for , the proposed method of calculating the single pile bearing capacity and settlement is particularly important . Therefore , this paper of Yongshou to highway Xianyang Xianyang Airport Interchange static load test , drilled pile bearing capacity characteristics of a serious study of the Guanzhong loess area . On the basis of test analysis further derivation of the pile top load - settlement relationship the analytical solution , the numerical simulation with ANSYS finite element analysis software , has made ??the following main results : 1 . Study the JCS1, JCS2, JCS3 three test pile flooding before and after load transfer behavior of axial pressure , including axial force distribution characteristics , to play a character and determination of the ultimate bearing capacity of the pile friction and tip resistance , and a comparative analysis before and after soaking . On the basis of the results of previous studies , reasonable simplified analytical solution derived digging pile in homogeneous soil single pile load - settlement relationship , Satoru Satoh Fixed load transfer function parameters and pile end settlement calculation used in the Winkler foundation model parameters , which must be discussed, and to be determined. The analytical solution is derived by the single pile load - settlement curve with the experimental values ??conducted a preliminary comparative analysis . 3 using ANSYS finite element analysis software model to further explore the single pile load transfer law , be top of the pile load - settlement curve , and the static load test values ??, theoretical values ??are compared and analyzed in order to verify this article deduced analytical solution of the feasibility .
