Backward in Tunnel monitoring and measurement and information technology is mainly because of the following aspects: ①Human element and construction influence the process of collecting data, make the measurement error, the authenticity of the data cannot be guaranteed, and cannot accurately reflect the deformation of surrounding rock. ②Automation of monitoring and measuring equipment and level of information technology are low, data processing workload, take up a lot of manpower, material, and error-prone, and cannot reflect the deformation of the structure timely. ③Data transmission, storage and information management cannot meet the informatization construction management's requirements, not guide the design and construction timely. ④Warning and forecast lag, cannot guide and solve the problem of the quality and security timely 3.

For the contact problems of internal rolling bearing, these assumptions are basically established. 1)the material is uniform; 2) contact region size is far smaller than the size of objects; 3) force perpendicular to the contact surface (contact area without friction); 4) in the elastic limit deformation[8].
Θ1 andΘ2 is the coefficient related to the material elastic modulus, Θ1=4(1-1/m12)E1,Θ2= 4(1-1/m22)E2，contact materials’ elastic modulus E1 and E2; 1/m1 and 1/m2 are the corresponding Poisson ratio; In the model material, elastic modulus E=207GPa, Poisson ratio is 0.3. ρ is the principal curvature of the contacting objects.
Now the bearing material is determined, the equation of a can be simplified as following equation(8).

Introduction 6061 aluminum alloy is widely applied in aeronautic, automobile, electronics and communications industries as one of structural materials because this alloy has excellent properties such as low density, moderate strength, good hot-workability and good corrossion resiatance [1,2].
And subsequent treatment can furtherly enhance mechanical properties to satisfy the needs of structural materials. 6061 alloy is one of deformation aluminum alloys, which contains magnesium and silicon as major addition elements and can be strengthened through heat treatment [3-4].
Material and experimental The experimental samples were taken from extruded 6061 aluminum alloy bar.
