为了研究静压桩在沉桩期间的力学特性和承载性状，通过静力压桩试验及载荷试验，分析了沉桩过程和载荷试验中摩阻力随埋深的变化；对非饱和黄土地区静压桩在施工过程中的承载性状及沉桩机理进行了研究，得出静压桩在非饱和黄土中的沉桩特性；将ANSYS计算值与实际测试数据进行对比，二者发展趋势较一致，说明ANSYS分析的结果可以为以后的工程设计和施工提供借鉴和参考。%In order to study the mechanism and bearing characters of static pressure pile in the process of pile driving mechanics,through the test and load test,static pressure pile under the premise of the introduction of sliding friction coefficient deduced the relationship between bearing capacity and final pressure,and static pressure under different loads under the bearing capacity of the pile and the relationship of the force that press a pile were analyzed;Static pressure pile in collapsible loess area in the construction process of bearing characteristics of pile driving mechanism was studied,and it is concluded that pile of static pressure pile is in unsaturated loess characteristics;Finite element calculation value was compared with the actual monitoring results,and the two were closer,and the trend of the development and change of consistent can show the results of finite element analysis for future reference and reference for the engineering design and construction.
