摘　　要：本文在现场试验的基础上,利用有限元法对各级试验压力下,通过有无测管时桩顶应力对比,分析测管埋设对桩体的影响性。A sliding micrometer theroy, with the advantages of high-precision, convenient use and wide prospect, is introduced in this paper. The measuring pile of sliding micrometer would decrease the cross sectional area and change the stress distribution. The finite element method is used to calculate the stress distribution of the pile in different experimental pressure, whether it has the measuring pile or not. Moreover, the effect of installing measuring pile on the cross sectional stress distribution of cast-in-situ pile is analysised.
