| Abstract: | In this paper,the field test results,numerical simulation results and theoretical calculation results of the real type test carried out in the west of Sichuan are compared so as to discuss the pile group effect and vertical bearing capacity of the micro-pile group foundation under the condition of silty clay stratum.The results show that the micro-pile group foundation has good compressive performance under the stratum conditions,and the ultimate compressive capacity of the test foundation can reach 2700 kN.The pile group effect coefficient obtained by solid perimeter method is most consistent with the numerical simulation method.In the preliminary design of silty clay stratum,the pile spacing can be calculated within the range of 4~5 times of pile diameter and the pile group effect coefficient can be calculated by solid perimeter method. |
