Abstract

Construction projects steps among the vast and varied construction has remarkable significance range in civil industry. Foundation as an important part of building the, is made of various systems in order to transfer the load from the superstructure to basis. In order to subsurface location checks could be used of identifiers such as boreholes, wells, trenches and in situ tests and laboratory tests. Project facilities are the most important factors to identification the equipment and tools. In this study, by using the results of the exploratory boreholes, field observations, in situ tests and laboratory studies have been consider to evaluate geotechnical condition of Erbil Altun kupri project site. According to this by studying the Geological Engineering condition of site project and Lefran tests, spt and cutting feathers standing on samples taken from boreholes from drilled and comparing results together, which generally consists of sand and gravel with fine particles of silt and Clay, has been determined geotechnical parameters of location. In the calculations after 6.5 meters excavation, location soil considered pre-consolidation and for settlement calculation, under layer soils were divided into several layers. The detailed results of calculations to verify foundation settlement before and after soil improving operation that used DSM method and it’s analysis by using Plaxis 3D software, showed the elastic settlement 0.0105 mm in the center of foundation.

Highlights

Geotechnical Science, study the different layers of the earth and groundwater as a factor in the stability and behavior of the structures favors
Geotechnical investigations will cause the optimum design of the structure if the bearing capacity of soil, be more than which assumed in the structural design, the project will be uneconomic and if the bearing capacity of the bed soil cause the soil disrupt and less than the given amount, certainly issues such as settlement, reversal and will at least create cracks instruments
Due to the need for geotechnical studies, consultant have to set these studies included in the schedule of the proposed project and to do necessary predictions .in this study in order to geotechnical assessment of excavation site soil of Erbil project, after surface identification stage,excavate four bore in soil of project location and have been tested the samples taken of various depths physically and mechanically and determined porterage degree and settlement of project location soil according to the tests results

Summary

Introduction

Geotechnical Science, study the different layers of the earth and groundwater as a factor in the stability and behavior of the structures favors. Domain and geotechnical investigations expansion should be determined according to the land location condition and dimensions of the structures and foundation. These discoveries should be done in stages and details of each stage should be determined according to data from the previous stage. Due to the need for geotechnical studies, consultant have to set these studies included in the schedule of the proposed project and to do necessary predictions .in this study in order to geotechnical assessment of excavation site soil of Erbil project, after surface identification stage ,excavate four bore in soil of project location and have been tested the samples taken of various depths physically and mechanically and determined porterage degree and settlement of project location soil according to the tests results
