Evaluation of Some Geo Mechanical Parameters of the Soil Samples from Ganakbari Area, Dhaka, Bangladesh

Geo mechanical parameters are evaluated here in. The unconfined compressive strength (q u) value ranges from o.38 kg/cm 2 to 1.60 kg/cm 2 and the average value is 1.06 kg/cm 2 . The analyzed soil is ‘medium to stiff’ based on ‘q u ‘. The UCS is closer to the typical strength for kaolinite and illite. The soil is brittle to ducti le in nature. The values of cohesion (C) vary from 0.1 kg/cm 2 to 0.6 kg/cm 2 in the Madhupur Clay. The values of the angle of internal friction ( ) vary from 7º to 34º. The values of cohesion decrease with increasing the values of moisture content. The obta ined values of ‘’ are closer to the typical values for illite and kaolinite. The shear stress increases linearly with increasing normal stress. The compression index (C c ) varies from 0.16 to 0.20 and the average value is 0.18. The soil samples are medium plastic based on compression index values. The compression index (C c ) increases with increasing the value of void ratios and moisture content. The soil might be normally consolidated to over consolidated in nature.

Some Mechanical Properties and Workability of Soils in a Karadeniz Agricultural Research Institute Field

2009

In this study, some physical and mechanical properties of Karadeniz Agricultural Research Institute soils such as field capacity (FC), bulk density (BD), relative saturation (RS), penetration resistance (PNR), Atterberg limits, consistency index (Ic), and suitable moisture contents for soil workability were investigated. Soil samples were taken from 0 to 20 cm depth. Soil in the Research Institute field was almost uniform according to clay content which ranged between 72.30 and 79.40%. Mean values for BD, FC and PNR of soils were determined as 1.06 g cm, 40.36% and 0.72 MPa, respectively. Atterberg limits of clay textural soils ranged between 71.98 and 92.14% for liquid limit (LL), between 36.33 and 43.73% for plastic limit (PL), and between 32.68 and 48.41% for plasticity index (PI). Soils in the field are classified as highly plastic and inorganic silts of high compressibility. LL values of soils significantly correlated with PL (0.618*), PI (0.903**), FC (0.860**), and RS (0.665*...

Investigation into some of the engineering properties of soil in Damot Gale district

2020

Investigation of the sub-surface condition is used for the effective design of the structural elements. It is also very crucial to obtain information on the type, characteristics, and distributions of soil and rock underlying a site for proposed structures. I investigate some of the engineering properties of soils collecting 20 disturbed and 10 undisturbed soil samples from 10 different test pits at the average depth of 1.5m to 3m and laboratory tests conducted. The natural moisture content of soil ranges from 24% - 44.47% and bulk unit weight range from 16.4 to 19.7 kN/m3. The specific gravity of soil varies from 2.57 to 2.84 and the particle size analysis showed that the dominant proportions of soils in the study area are the clay. Consistency limit test results in the research area showed the liquid limit ranges from 46 to 73%, plastic limit ranging from 13 to 38%, and plasticity index ranging from 13 to 38 %. The unconfined compressive strength of the soils in the study area ran...

Assessment of physical properties of soil in Kalimpong district of West Bengal, India

International Journal of Chemical Studies

The objective of this study was to analyze various soil physical properties. Samples were taken from two profile depths viz., 0-15 cm and 15-30 cm from three different villages in entisols of Kalimpong district. Data revealed that bulk density increases with depth and ranged from 0.83 to 1.11 g cm-3. Texture varied from clay loam to sandy clay loam. Water holding capacity ranged from 60.40 to 71.05% and percentage pore space from 55.5 to 61.5%. Significant variation in soil physical properties was recorded both due to site and due to depth. Particle density and specific gravity remained unchanged for most of the soil. Soil colour varied from brown to yellowish brown colour in the dry condition while dark brown colour predominated in the wet condition. The results revealed that the soils were in good physical condition due to adoption of organic farming in Kalimpong.

Soil Analysis Test Results is then compared and few conclusions are obtained from the test reports. Basic interpretations can be drawn for the improvement in soil from the comparison.

Geotechnical Characteristics of Two Different Soils and their Mixture and Relationships between Parameters

2012

This paper describes the physical and engineering properties of three different types of soil. One has been collected from NIT Agartala campus and other from River bank of Howrah from different locations of State of Tripura, India. A mixture of both the soils is also investigated. Laboratory tests have been conducted on grain size analysis, specific gravity, Atterberg’s limits, standard Proctor compaction, direct shear, and one-dimensional consolidation to find out various parameters. As clay content increases in the soil, the plasticity index (PI) increases and angle of internal friction (φ) decreases; with the increase of plasticity index, optimum moisture content (OMC) of the soil increases. As liquid limit (LL) increases, compression index (Cc) increases. With the increase of OMC, Cc also increases. Correlations have also been established; PI, OMC and Cc found out with the help of other parameters.

Appraisal of Geotechnical Characteristics of Ormara Soil, Baluchistan, Pakistan

International Journal of Economic and Environmental Geology

Ormara is located 240 km west of Karachi which is a coastal and port city (25° 16' 29N, 64° 35' 10E) ofPakistan. Present study evaluates engineering properties of soils of Ormara for future construction plans and possibleexpansions in the area. Fifty bore holes were done in study area at depths of 20m, 40m and some (10 bore holes) were60m deep. The study area was divided into three major zones i.e. Foot hills, on-shore and off-shore. Groundwater wasencountered at depths of 2.75m on onshore and offshore zones and at 3.65m depth in foothill zone. Laboratory testingi.e. moisture content (12 to 38 %), liquid limit (from 26 to 34), plasticity index (10 to 18) of soil samples indicate thatsoils are low plastic to moderate plastic in nature.
