Estiamtion of the Liquefaction's Risk of a Soil Deposit under Seismic Solicitations: Petrochemical Zone of Skikda city Sbartai Badreddine1.a, Fillali Kamel1.b 1 LMGHU laboratory, University 20 Août 1955-Skikda, Route el-hadeik, 21000 Skikda Algeria a bsbartai@hotmail.fr, b fkamel2009@gmail.com Keywords: liquefaction, risk, soil, earthquake Abstract: This study consists in estimating the risk (potential) of liquefaction of a soil deposit saturated when it is submitted to a horizontal seismic excitement to its basis while using the approach in total constraints.
For the determination of τl, the graph of Seed and al based on the results of the SPT.
In second place, we used the curve of resistance according to the deformation developed by Seed and al [2] in order to evaluate the constraint of cyclic shear of the same soil.
To evaluate the cyclic constraint of shear τl, we use the empiric resistance curve as the one developed by Seed and al [2].
While using the curve of resistance of Seed and al [6], we have gotten the cyclic constraints of shear in the deposit of sand.

The thermophysical properties of the ground and air were consistent with those used by Vaz et al
Additionally, the findings from this study were compared with numerical values from the models developed by Brum et al. [13] and Rodrigueset al. [14], for the identical geographic area, with the aim of also performing a verification.
Additional details regarding this indicator are provided in Rodrigues et al. [14].

Introduction Since the aluminophosphate molecular sieves were first synthesized in1980s by Wilson et al.[1], the study on synthesis method and exploring new metal ions has become a hot interest increasingly.
While in the synthesis of NiAPO-5, we also followed the hydrothermal synthesis (HTS) methods and the composition ratio was: Al: Ni: P: TEA H2O: HF = 0.97: 0.03: 1.0: 0.75: 25: x(x=0.2~0.35).
The characteristic peaks at about 721, 1120 and 1130 cm-1 were assigned to the O–P–O bending vibration, P–O stretching vibration of PO43-, and stretching vibration of Al–O in combination with P–O, respectively [12].

Recently, Gentleman et al.[3] reported that strontium substitution in bioactive glass created a biomaterial with a renowned anti-osteoporosis effect.
These results are in agreement with O’Donnell et al. [10] who reported that the effect of increasing strontium content in the bioactive glass promotes the formation of apatite on the glasses.
The formation of the apatite layer may contributed by the combination of the calcium ion and phosphate ion which forms amorphous CaO-P2O5 on the silica rich layer as proposed by the Hench et al. [11].

One of the first studies carried out aimed to understand the mechanical behavior of the material was developed by Gonzalez et al [1];. they studied the behavior to the shear test of beams laminated of guadua Angustifolia Kunth with three different adhesives; likewise, Gonzalez et al [2] studied the bending behavior of beams for two different rectangular cross section and double T cross section.
Estrada [5] investigated the possibilities of design and construction of structural elements of laminated guadua; Varela [6] studied experimentally the behavior of panels made with laminated guadua used as shear walls; Quiroga [7] studied the influence of nodes and finger joins in laminated guadua, Atoche [8] evaluated the structural behavior of joins between laminates that make up the element of laminated guadua; Luna et al [9] carried out tests to study the compression behavior of columns for two types of cross section.
