Abstract:

On basis of the actual situations of the boring of the shield machine in soft ground and hard ground, the article makes analysis on the influence of the ground conditions on the boring of the shield machine, from which the boring parameters of the shield machine in soft ground and hard ground are obtained. Then the article compares the boring parameters in soft ground with those in hard ground. On basis of the anaylsis on the special incidents encountered during the boring of the slurry shield machine in various grounds, the article recommends the relevant countermeasures so as to facilitate the construction of the tunnel and to extend the service life of the shield machine.
