The effect of a shield crossing an existing underground infrastructure needs to be evaluated, yet there are few studies on this subject.
In this paper, a new analytical method is proposed that uses a Timoshenko beam to simulate jointed shield tunnel responses when subjected to an adjacent excavation, which can consider both the bending and shearing effects of a shield tunnel.
It was found that the silicate ions on SiHA (100) surface cause a shield effect, which was composed of the charge repulsion and the steric hindrance of silicates.
This effect of MWNTs can be called a shielding effect and it represents the leading effect after the first 5 min [ 35].
The director, Blair Hayes, uses Mr. Gyllenhaal's pointy-chinned naïveté for enthusiastic comic effects; having grown up inside a shield means he has no protective social membrane either.
A measure passed by the Legislature in 1985, which addressed the withdrawal of treatment for terminally ill patients, created "public policy," the majority said, that in effect shielded a physician from prosecution for helping hasten the death of a consenting, rational, terminal patient.
In the next part of this section, we will try to explain and describe the shielding effect a bit more deeply than in our previous works [28 31].
The liberal interventionism that the movie's dénouement depends on — the British Army's deliverance of the BFG from the clutch of the crude, cruel, and ignorant colossi — is, in effect, a cultural policy that would shield the virtuous dream-workers from the depravities of corporate overlords.
In this paper, a new approach to take into account a shielding effect is presented.
It is found that a square hole has a shielding effect on crack(s) emanating from the hole.
It is found that a circular hole has a shielding effect on the SIFs of crack(s) emanating from the hole.
