At the beginning, an engineering method called semi-empirical reliability estimation method is introduced. Then, a detailed introduction of the bootstrap method, which has been widely applied to small sample reliability assessing since it was proposed in 1979, is made immediately. At last, a promoted virtual sample expanding method, that the reliability test sample size is expanded from 2-3 to 10, is proposed on the basis of predecessors research results. And the new method associated with bootstrap method is used to assess the test life lower limit in the case of logarithmic normal distribution.

In the foreword, it is the brief analysis of the creative process of the creative subject, telling readers that what we concern about is the study of the subcreative of the creative subject and the study method and the study content of the dissertation. In the first part, it begins with the definition and the process of the subcreative, stepping into the case study of Ge Fei's subcreative, that is what we will study in the dissertation. In the second part, we try to find out the process of Ge Fei's subcreative according to the study method we mentioned in the foreword through the text analysis of the imago combination and the emotion stream in the Ge Fei's texts. In the third part, we summarize how the times and the readings influence the creative subject, through the analysis of the time when Ge Fei lives and the experiences of Ge Fei's reading. In the epilogue, we generalize the significance of the study of the dissertation, hoping that the Ge Fei's case study we do can give the subsequent researchers some revelation.

First, this paper presents three girders model with double cable planes which main girder and side girder is connected by rigid arms, analyzes the dynamic characteristic of Yonghe cable-stayed bridge and obtains its natural vibration modes (i.e., frequency, damping values and the mode shapes ) by ANLSIS structural analysis program and uses these parameters as dynamic dactylogram of the intact case of cable-stayed bridge. Using the passage of random as the ambient vibration ,the dynamic properties of Yonghe Bridge is measured and the modal parameter of its 15 years after is identified and used as dynamic dactylogram of the damaged case. By the finite element analysis and locale vibration test, damaged and undamaged modal parameter is analyzed and curvature mode shape, which is sensitive to damage state, is introduced as possible candidate for identifying and locating damage in the cable-stayed bridge. Selecting the branch of part measured point from modal parameter, this paper deduces the damaged index which can detect the possible damaged location of the cable-stayed bridge deck and identifies the damaged region and degree for Yonghe Bridge. For the purpose of structural condition monitoring in in-situ , from another viewpoint, this paper introduces the method called the best optimization vector to detect damaged location and degree. The accuracy and reliability of the method presented in this paper are demonstrated by static analysis and test and the healthy state of Yonghe Bridge can be evaluated.
