For civil airline company, the problem was usually solved by the advanced maintenance mode----condition based maintenance.
So it is necessary to establish a military aero-engine DEGT estimation method combined with civil aviation aero-engine DEGT calculation method.
This method has been extensively used in civil aviation condition based maintenance [1-5].

Introduction Based on bored cast-in-situ pile foundation engineering of a sluice, the three dimensional model for the foundation is set up by ANSYS[1].
The actual engineering pile endpoint soil modulus for 400 MPa, through the analysis of the pile endpoint soil take elastic modulus E = 4 MPa, E = 40 MPa, E = 4000 MPa, E = 40000 MPa and actual engineering calculation results are compared and analyzed.As shown in table.3, it is known that the pile soil each part and to the whole of the deformation as E and decreases, the largest body stress and pile body maximum stress increases with the E.

Laws of fatigue damage Deformation of engineering materials develop in three stages under cyclic loading associated with cycle times generally, which are formation stage, steady expansion stage and instability stage of internal damage [6].It is indicated in Figure 6 that the transition of plain concrete is not obvious between the first and second stage, the first two stages account for 85% of the fatigue life, and the initial strain is larger than HFRC.
