Geotechnical investigation is undertaken to obtain information on the physical properties of soil and rock underlying a site to design a proposed structure and for repair of distress caused by subsurface condition. With limited geotechnical data, a designer has to determine which correlations produce safer design values, define critical project areas, and gage how soil mechanical properties change with depth. Characterizing soil engineering properties and analyzing their spatial pattern has a key role in managing soils for dif- ferent land uses. Geotechnical engineering investigations need to be performed by engineers or engineering geologists to gather important information regarding the physical properties of soil and foundations.

Abstract â Swiftly expanding populace everywhere throughout the world is in direct extent to the advancement programmes in lodging and development of modern upgrade. In the construction field, it is an important process as it improves the engineering properties of soil to a great magnitude. Clay-size mineral particles, regardless of mineralogy, exhibit behavior unlike granular-size (i.e., silt and sand) particles. Geotechnical Services should present sufficient information for the Engineer to perform shoring design and analyses. The information presented in the tables is useful to indicate the general range of values for typical geotechnical properties, but is no substitute for site-specific laboratory and field information. Both lateritic soils and andosols are susceptible to property changes upon drying, and exhibit compaction and strength properties not indicative of their classification limits. Considerable studies have been carried out on the geotechnical properties of laterite soil by various researchers [12], Amadi et al, 2015. The geotechnical properties of soil is found to be greatly affected by increase in concentration of oil among the various percentage of contaminant. Preliminary tests were carried out on the natural soil sample for identification and classification purposes, while consistency limits tests were thereafter carried out as well. He found that the liquid limit, plastic limit, strength and permeability of the soil decreased as the diesel content increased. The main target of this research is the determination of geotechnical index properties of soil by employing geophysical and geotechnical techniques. Numerous kinds of stabilizers are being used as soil additives to improve soil engineering properties such as lime, cement and fly ash, depending on their chemical reactions with the soil elements in the presence of moisture. The development of soil and rock properties for geotechnical design purposes begins with developing/defining the geologic strata present at the site in question. Therefore, the focus of geotechnical design property assessment and final selection shall be on the individual geologic strata identified at the project site. The constraints of each site, geological and geotechnical properties, project requirements and geophysical principles on which is based every method of investigation guide the choice of the best technique to use.

The soil conditions can range from underconsolidated sediments to rock.1, 2 In addition, the engineering properties of soil deposits may vary horizontally across different geologic provinces as anticipated, but can change unexpectedly with depth as well. Prefabricated vertical drain spacing may range from 0.7 m to 2.7 m. ASTM's geotechnical engineering standards are instrumental in specifying, testing, and investigating the physical/mechanical properties and characteristic behaviors of surface and subsurface earth materials that are relevant to a construction project. Geotechnical testing methods are used to get critical information about the physical properties of the substrate, rock, and soil around a potential construction site. Underneath there are alternating sand and clay layers. Thus, it is always recommended to hire a professional geotechnical engineer prior to any design and construction plans. This book presents traditional soil mechanics theory with applications to various geotechnical situations and gives students the background on soil and soil origins necessary for predicting deformation, strength, and flo water in the the soil mass.

Soil structures. Rahman (2010) observed that oil-contaminated soils indicated a lower Maximum Dry Density (MDD) and optimum water content compared with uncontaminated soils. Four tables are presented in which descriptive and interpretive properties of soil and rock materials are correlated with their genetic classification. ABSTRACT The study of geotechnical index properties of soils in Warri, Delta state was carried out to determine the index properties of soil. The Unified Soil Classification System (USCS) is a standardized way for geotechnical engineers to describe soil. Soil testing program is an analysis of the soil physical (chemical or biological, if applicable) properties. 6 uses the principles of soil mechanics and rock mechanics for the solution of its respective engineering problems. All interpretations of geotechnical data will involve a degree of uncertainty because of the differing origins, inherent variability, and innumerable complexities associated with natural materials. with Collier Property Management and performed in accordance with Proposal No.G&AI P15-0313 dated June 24, 2015.
