“…Table 1 presented by Townsend [1] shows the shear strength parameters for the above-mentioned soils that had been obtained in previous studies. Loganathan et al [4] suggested a correlation factor for shear strength of residual soil in order to achieve more accurate results. This correlation factor can be applied into the laboratory shear strength of a specific type of residual soil that has been obtained by specific method of sampling and testing.…”

This paper investigates slope stability of soil nailed walls which are located on sites formed with mostly residual soils. Residual soils, forming from weathered rocks can be found in many parts of the world with different characteristics and appearance based on type of the parent rock they have been formed of. A review on geotechnical properties of residual soils that have been used in previous studies in different parts of the world will be presented and then evaluated to be used as parameters for numerical analysis of soil nailed walls. Slope stability assessment is performed by LEM analysis and a discussion on the results of analysis is presented in this paper.

“…Such cases occur when the soil is heterogeneous and where the soil is composed of clay minerals such as allophane and halloysite (Pitts and Kannan, 1987;Loganathan et al, 1992;Morin and Todor, 1992). The Atterberg limits, particle size distribution curves and specific gravity of some residual soils depend on the nature of pretreatment prior to testing such as whether the material is tested at natural moisture content, air-dried or oven dried and remolding process (Loganathan et al, 1992). The apparent grain sizes are usually larger than the actual ones and thus the percentage of clay-sized particles is underestimated.…”

A detailed study was performed to investigate the compressibility and the shear strength of a residual soil in Omdurman, Sudan. The soil resulted from weathering of sandstone and mudstone. The soil is classified as sandy clayey silt (MH-CH) and is generally partially saturated. Consolidation tests were performed to study the compressibility of the soil and UU, CIU and insitu tests (CPT and SPT) were performed to study the shear strength characteristics of the soil. The characteristics of this residual soil can generally be predicted using correlations proposed in the literature for transported soils. The soil is of low to medium compressibility and exhibits slight apparent overconsolidation behavior. The soil dilates during shear and shows no long term effective cohesion. Problems associated with open cuts in this soil are attributed to loss of strength upon saturation.

“…In-depth study on the engineering mechanical properties of the highway building in basalt residual area is important to elevate the highway construction technology in basalt residual area. Scholars have researched on physical and mechanical index [7][8][9][10], permeability [11,12], strength [13], disintegrative [7,14], mineral composition [15] and microstructure [16]. The previous studies indicate that different basalt residual soils of varioius regions show the similar engineering mechanical properties and also their respective regional characteristics.…”

The basalt residual soil of high slope of BiWei highway in Guizhou province belongs to regional special soil. Comprehensive and systematic evaluation for engineering geologic characteristics of residual soil on basalt is necessary to the construction in this area and geological engineering investigation. Kaolinite is dominant in clay mineral of this soil, which has a higher clay particle content. The special material composition and structural morphology make it have the physical properties of high porosity, low density and high water content. But it has mechanical properties of higher strength. The soil has a low expansibility and weak water-resistance. Moreover, the soil is sensitive to environmental factors such as temperature and humidity. The mechanical properties become weak after soaking, leading to a larger collapse deformation and a heavy disintegration. Therefore, it is important to focus on the engineering disasters caused by rain water for example.
