Sentence examples for backfill effect from inspiring English sources

Water backfill effect may occur when the unsaturated wetting front encounters a fine layer underlying a coarse layer.

Water backfill effect occurs in coarse layers between upper and lower fine layers when the lower layer is not significantly coarser than the upper layer.

To avoid the disadvantages associated with downward mining and overhead backfilling with this new technology, a new advanced solid backfill mining design with two pre-driving entries is proposed here to ensure the backfill effect.

The features of the model are as follows: (1) pipe deformation and gas decompression are formulated based on one-dimensional partial differential equations; (2) the interaction among pipe deformation, gas decompression and crack propagation is considered; (3) soil backfill effect, which constrains pipe deformation, is considered as added density.

At the mining height of 3 m, even if the backfill effect is poor (q = 0.3), the damage of ground buildings still can be protected within level I under the supercritical panel width, whereas at the mining height of 5 m, as the filling effect get worse (i.e., subsidence factor of 0.2), the damage level of surface structures begins to be > I (Fig. 3).

The impact of jacket application incorporated in more complex numerical models considering soil-structure interaction, bearings at expansion joints (pounding and unseating), and abutment backfill soil effects, with the inclusion of pile-footing-pier failure would be contributory in this area.

A series of finite element simulations were also fulfilled on two real rectangular tanks subjected to backfill and fluid effects.

Figure 6 indicates that the variation of Young's modulus in the backfill has negligible effects on the distribution of horizontal stress when compared with the variations in the friction angle.
