ZHANG et al [10] studied the seismic coefficient of earth- rockfill dams with the height more than 150 m.
Table 1 The computational cases Wave Seismic intensity Height of the dam(m) Width of the valley(m) Slope ratio of the bank (1) Taft wave (2) El Centro wave (3) Banshen wave (4) Shenhu wave (1) 7° (2) 8° (3) 9° (1) 100 (2) 150 (3) 200 (4) 250 (5) 300 (1) 50 (2) 150 (3) 300 (4) 500 (1) 0.4 (2) 0.6 (3) 0.8 (4) 1.0 (5) 1.5 The crest width of the dam is 10m, the slope ratio of the upstream and downstream are 1:1.6, the density of the rockfill is and the density of the concrete faceplate is . 3 Results analysis From Fig. 3,4and 5 it can be seen that when the earthquake intensity is 8 degrees and 9 degrees, the distribution of horizontal acceleration along the dam height at the central points on the central section of concrete-faced rockfill dam behaved like the earthquake intensity is 7 degrees but the seismic coefficient becomes smaller accordingly.

On the other hand, the research of Guoqiang Fan et al. formed Ti-6Al-4V titanium by incremental forming at high temperatures showed that the incremental forming on the Ti-6Al-4V titanium at temperatures of 500-600°C by use of a lubricant film of nickel and molybdenum disulphide had, as a result, improved the formability [2].

EDS analysis shows that the as-deposited trivalent chromium coatings is composed of Cr, P, C, O and some Na and Al inclusion, as shown in Fig. 3.
The XRD pattern of Fig.4 of the as-deposited and as-annealed depositeds indicates that the phase structure of the chromium coatings evolved from amorphous to microcrystalline or crystal when annealed. 0 150 300 450 600 750 900 450 600 750 900 1050 1200 1350 Cr(III) deposits Cr(VI) deposits Hardness/HV t/° )Χ 0.0 1.5 3.0 4.5 6.0 7.5 Cr KeV C O Al P Cr Na 30 40 50 60 70 80 90 (b) Cr coatings annealled at 400°C for 1h 2θ/(°) (a) as deposited Cr coatings Fig.2 Hardness of hexavalent and trivalent chromium, 2h.

Geometry and transverse section description of structures Input ground motions In order to define input motions to linear (EL) and nonlinear (NL) dynamical analysis, a selection of recorded motions is used.
The adopted earthquake signals are proposed by (Ievolino and Cornell; Bradley and al. and Sorrentino et al.) [12,13 and 14].
