1. [radio] tunnel site supervision measure will test the project is ().
A. internal displacement of surrounding rock (cave site points)
B. Surrounding the displacement body (surface set point)
C. rock pressure
D. peripheral displacement
The correct answer: D
Reference Analysis: will test the project must be carried out when the tunnel construction have observed outside the cave, the surrounding displacement, vault subsidence, surface subsidence 4, the remainder being selected test items. Internal displacement of surrounding rock (cave site points), internal displacement of surrounding rock (ground set point) and not in the four rock pressure must be measured, the options ABC error. Therefore, the correct options to this question is "D. peripheral displacement."
2. [multiple choice] tunnel at the time of the measurement surface subsidence project should be used () were measured.
A. Level
B. Geological Compass
C. measuring tape
D. Indium ruler
E. spindle
The correct answer: AD
Reference Analytical: Measurement tunnel site monitoring items and measuring method: When the surface subsidence project, leveling method using leveling tools, indium ruler.
[3] multiple choice tunnel measurement hole, the outer observation items should be used () is measured.
A. Level
B. Geological Compass
C. observation site
D. pressure cell
E. Total Station
The correct answer: BC
Reference Analysis: measuring tunnel hole, the outer observation items, methods and tools for field observation, geological compass.
