- W2368116753 abstract "Research purposes: China is the world's most populous country in the tunnel that usually use the drilling and blasting method. Advance geological prediction of tunnel construction method of choice, the safety of tunnel construction,step distance and the tunnel excavation footage control are four key problems in tunnel construction. In view of these problems,there are some cognitive biases and error approach in construction field,seriously affect the safety of tunnel construction. Therefore,must carry on the discussion and research on these key problems,in order to ensure the safety of the tunnel construction.Research conclusions:( 1) Advance geological forecast shall have special design,in view of the different geological shall take reasonable and effective method,should further clarify the advance geological forecast expenses and liability.( 2) Step construction,the step height is 2. 5 m,to facilitate the rapid positioning that at the top of the installation of steel frame positioning,is conducive to the construction safety,step length should be 1 times of the diameter of the tunnel.( 3) The construction safety step is an effective measure to step construction safety,mandatory implementation.( 4) The excavation footage control is an effective measure to prevent the loss of stability of tunnel face,must be strictly controlled in the construction step method.( 5) Research results can be applied to the bench method for construction of railway tunnel." @default.
