يمثل هذا البحث محاولة إنشاء قاعدة معطيات أولية عن تجارب تحميل الاوتاد البيتونية المدقوقة في التربة الرملية, و قد اعتمد البحث على تحليل عدد كبير من منحنيات تجارب التحميل المتوفرة و تقييمها, و درس تغير قيمة التحمل الحدية للوتد المأخوذة من تجارب التحميل بدلالة عدة بارامترات (الكثافة النسبية للرمل, طول الوتد المغروز في الطبقة, قطر الوتد المدقوق), و بناء على النتائج اقترحت علاقة تقريبية أولية لحساب قوة التحمل الحدية للاوتاد المدقوقة في الرمل, و من ثم أجريت مقارنات بين الطريقة المقترحة و بين الطرائق الحسابية التحليلية كذلك بينها و بين نتائج الحساب وفق بعض الكودات العالمية المتوفرة (الامريكي, الروسي, الالماني). تقدم العلاقة التقريبية طريقة سهلة و بسيطة لحساب قوة تحمل الوتد البيتوني المدقوق في التربة الرملية بحسب درجة ارتصاصها, و طول الوتد المغروز فيها و قطره, و يمكن اعتبار الطريقة المقترحة مقدمة للمتابعة في تطوير البحث ليشمل أنواعاً أخرى من الترب.
This research represents a trial to establish a primary database of load tests applied on concrete driven piles embedded in sandy soils. This research depended on analyzing and evaluating a large number of available load test curves of driven piles. The variation of pile ultimate bearing capacity value is studied according to several parameters such as (relative density of sand, embedded length of pile and pile diameter). Depending on the obtained results a primary approximate relationship is suggested to calculate the ultimate bearing capacity of driven piles in sand. Then, a comparison is made between the suggested method and the other analytical calculation methods and also, with the obtained results from an available international codes of practice in America, Russia and Germany. The approximate relationship introduces a simple and easy method to calculate the bearing capacity of concrete driven piles in sands. Also, This suggested method may be considered as an introduction to developing the researches to include different kinds of soils.

A parametric study of pile load test requires a numerical modeling of this test and a study of the effect of each parameter of the material model used on pile load settlement curve shape and on the extrapolated value of pile ultimate bearing capacity
. Some real pile load tests are numerically modeled and calibrated using two types of material models: Mohr-coulomb MC and Hardening soil HS. The obtained results from HS are better than those obtained from MC, so material model HS is adopted to generate pile load settlement curves. It is shown that the relation between the extrapolated value of pile ultimate bearing capacity and each parameter of the material model used is linear, and there is only one value for each parameter of HS in which the calculated value of bearing capacity identifies with the normal value in DIN-Code. The main economic benefit obtained from this research is the ability of generating pile load settlement curves in addition to doing a parametric study using a numerical modeling method without any need to do pile load field tests. The practical scientific aim is to accumulate and collect information that can be used as a database for static pile load tests.
The problem of slope stability is considered as a main geotechnical problem due to the
significant damage (material or moral) related to failure. This paper aims to study the
influence of piles on the stability of slopes loaded with strip footing a
nd investigating the
parameters affected on stability (location of pile row relative to the slope crest X , piles
spacing S , piles length L and edge distance of the footing b ). This study has been realized
in two phases : the first phase consists in establishing a numerical model for sand slope by
using finite element analyses program (FLAC3D) and determining the footing settlement at
crest of slope before using piles and after reinforcing , after that the numerical results is
compared with the experimental ones (reference case ). A close agreement between
experimental and numerical curves is noticed .The second phase deals with studying the
influence of most important parameters such as ( piles length ,piles spacing, pile row
location relative to the slope crest on stability and edge distance of the footing) on the
slope stability. The results of parametric study have shown the piles installed near the slope
crest is more efficient in reinforcing where the safety factor is increased by reducing the
distance between row of piles and slope crest and the greatest value for safety factor when
X=0.7Lx . The currently study showed the efficiency of piles to increase the ultimate
bearing capacity with increasing edge, after that at b=3B the increase in ultimate bearing
capacity decreased. Also the slope stability depends significantly on pile length and it
increases even reaching the length equals the height of the slope. At other hand, the safety
factor is reduced by increasing the piles spacing, so that the efficiency of pile is
disappeared when pile spacing equals to six times pile diameter(UBCR<1.1).
Walls piles supported with Anchors are considered one of most ways of engineering supporting widespread. This research includes studying the behaviorof walls pile, through a numerical parametric study using the (plaxis / 2D) program. the study includ
es the most influencing factors which include:(the angle of the inclination, the vertical spacing between the rows of Anchors andthe distance of the first row of anchors from the ground surface). The effect of these factors on the stability of the wall was studied.Where they give the best effect to the anchors and ensure the best possible positioning which contributes to reducing the economic cost of this constructions.
The issue of export has become a main focus of economic policy-making states,
given that exports are an important engine in the process of economic growth. So countries
seriously seek to develop their exports and improve the export capacity through
the
adoption of an export development strategy. There are many international experiences in
this field, which have achieved remarkable success in improving their export performance
and raising the level of their economic performance. When studying the reality of Syrian
exports, it is evident that they suffer from several weaknesses negatively reflected on the
reality of the Syrian economy. This research aims to address those points, depending on the
strategy of developing exports applied in different countries of the world, representing an
important developmental policy and a means for boosting economic growth. It also aims to
highlight the possibility of benefiting from successful experiences by formulating a
national strategy for the development of Syrian exports in order to improve their position at
foreign markets and achieve stable and high growth rates.
This research aims to study the deformations creep in clayey soils
treatment with calcium chloride.
Creep experiments were carried out on samples of soil was added
with different ratios of calcium chloride compound, was measured
deformations with time and monitor the impact of the proportion of
calcium chloride added to the soil to these deformations.
