At this point,operating units must be carefully designed in order that there shall be enough time for the operator to deal with materials, machine maintenance and walk. 2.2 The analysis of economical efficiency Co is set for the hourly labor cost of the operator, Cp is set for the hourly cost of the machine and TC(p) is set for the cost of each machine that is operated by one worker.
Besides, the clamping operation usually includes picking up materials, and the Worker should walk to the place where the roughcast exists and then get back.

But the static load test needs large labor power, materials and financial resources and so on.
The material of pile is C30 concrete and the elastic modulus Ep=3e10Pa, poisson ratio μp=0.1667.
Such as the plate shape on theoretical analysis and pile body material and soil homogeneous assumption.
