2. Relationship between the number of blows and compress­ ibility Most of the above investigations are concerned with rela­ tionship between the number of blows and the relative density of soil strata. Since the relative density of various types of soil is related to compressibility (M o u s s a, 1960) there is a

Some experimental data from the literature (Sinha and Wang, 2008) are used to develop the EPR models.Table 1 includes the gradation properties of soils, Table 2 contains the compaction test data as well as some physical properties, and Table 3 summarizes the permeability test data. Data are from a soil made of four different major components—gravel, …

It is well known that the permeability coefficient of homogeneous soil is independent of the soil thickness. Therefore, according to the hypothesis in Section 3 and 4, both the interfacial soil permeability coefficient K i and the far-field soil permeability coefficient K p are independent of the thickness of the interfacial soil. This can also ...

Moreover, subfigure (b) underscores the inverse relationship between the gradation coefficient and the abundance of fine particles within the aggregates. Larger gradation coefficients correspond to lower fine particle contents, indicating reduced particle packing and an augmented presence of microcracks.

In this study, compaction tests of crushed solidified soil were conducted by varying the original soil, type of solidifier, standby time and curing time, respectively, and the results …

Then, the compaction quality was gauged considering different indexes such as relative density (D r ), degree of compaction (K), coefficient of subgrade reaction (K 30 ) and dynamic modulus of ...

Relationship between Compaction Ratio (RC) and Compacted Layer Thickness Yahya K. Atemimi Ph.D. in geotechnical engineering – civil engineering department, University of Babylon – Iraq ... failure to achieve proper soil compaction [1]. Sub-base soil is a granular soils constitute an important group of soils of one of the desert districts of

of crushed stone base. This scale was not based on any par-ticular method of test. Each highway agency was left to adopt a test method and establish or select a relationship between that test and the "soil support" scale. Without an analytical basis and a unified method of test, there was little possibility of improving the soil support scale.

To determine the relationship between roller and in situ compaction measurement parameters, it is necessary to conduct a series of in-situ tests on the subgrade soil. The in-situ compaction measurement parameters mainly include the modulus of subgrade reaction ( K 30 ) [ 28 ], the dynamic deflection modulus ( E vd ) [ 29 ], and the shear wave ...

JDS-3 standard portable compactor is used to determine the relationship between soil density and water content, thereby determining the maximum dry density and the corresponding optimal water content. ...

The soil–rock mixtures in the specialized engineering geology of fault zones are the focus of research. Unlike previous studies on the permeability coefficient of soil–rock mixtures under a singular stress state, this study …

Nielson (5) has established a relationship between the modulus of soil reaction, E' and the modulus of elasticity of the soil, E, by using the theory of elasticity. He con­ cluded that the modulus of soil reaction, E ', can be approximated by, Es (1 - us) E = 1.5 M* 1.5 (1 + Us} {l - 2us} where E' = modulus of soil reaction, psi;

Relationships between electrical soil parameters and soil compaction were modelled with the use of two types of neural networks—multilayer perceptron (MLP) and radial basis function (RBF).

Scholars have conducted extensive studies on the compaction and bearing characteristics of lateritic soils [7], [8], [9].Regarding compaction characteristics, Bille et al. [10] found that the varying moisture content affects the compaction characteristics, and the distance between soil particles under compaction gradually becomes wider with increasing moisture …

Using k i values more typical of a cohesive soil (e.g., 420, 0 and -0.6 for k 1, k 2, and k 3, respec- tively) results in a modulus profile more representative of the observed behavior (see Figure 4.8d) with modulus ranging from 37 MPa at z = 0.25 m to 71 MPa at z = 1.0 m (0.8-3.3 ft).
