摘　　要：针对混凝土扩盘桩桩周土体破坏机理研究过程中,现有半面桩小模型埋土试验方法和大型桩实体试验方法的局限性,提出了半面桩原状土模型试验方法,并阐述了该方法的试验步骤,指出该试验方法不仅能够真实的模拟桩土相互作用,全程观察土体的破坏形态,并且实施过程相对简单、安全、成本低廉。Due to the existing small model soil burial test of half section pile and large entity pile have a certain limitation,it makes the study of the Concrete Expanded-Plates pile failure mechanism get into trouble when in the process of researching the failure mechanism of soil around the Concrete Expanded-Plates pile（ the CEP pile）. This paper put forward the experiment method of undisturbed soil model of half section pile. And elabo-rated the test steps of the method. This method not only can simulate the real interaction of piles and soil and observe the failure behavior of soil in all groups,but also the implementation process is relatively sample,safe,and economic.
