In this thesis, the engineering property of the frozen earth in the frozen railway roadbed in Anduo section (between DK1561+975-DK1562+530) of Naquhe region of Qinghai-Tibet railway was studied indoor. The change of engineering property of the earth samples with different water content , density and temperature were researched. The influence of concentration of the diffluent salt to the frozen strength was pilot studied. The thermal conductivity of the soil was experimented. With the result and data of the tests, the earth temperature field in Anduo section was demonstrated by numerical analysis, the structure parameter of the spall revetmentd and the rubble berm was given, the stability of the railway roadbed was evaluated.

The management under the modernity make the chair in university become a quantitative posatition,the posation generate power through symbol,the formulable academic posation generate strong discipline power.Academic creation become a plan project,individuals face a giant engineering structure,the individual moral sensitivity ebbed away. Bestir excessively make arousal become chastisement.Academic activity is making difference and competition in the control of currency, and academic activity become monetization. Academic estimation become a shortterm action.

现代性之下大学的管理使得大学的学术职位演变为一个数量化的位置，这一位置利用符号产生力量，&公式化&的学术位置制造了强大的规训力量；学术创造变成规划性工程，个人时刻面临着非个人的巨型工程结构，个体的道德敏感性泯灭其中；激励与惩罚在现代性之下分界线模糊，对学术激励的过分使用使学术激励其演化成了学术惩罚；大学内学术在货币指挥下正不断地制造差异与竞争，学术货币化；学术考核则演变成一种短期行为。

Based on the systematic study of fault gouge characteristics (such as minerals component, granulometric composition structure and fractal, maturity, present activity and topotaxy by the SEM), a new way using microscopic and quantitative characteristics of fault gouge is put forward to evaluate the aseismatic problem and the fault resistance problem of concealed fault.
