“…First, an investigation towards a volcanic soil on its shear behavior has been tested, combing its microstructure. According to the research, Ulusay et al (Avşar, Ulusay et al 2015) adopted five places' soils and applied two different types of shear strength to detect the soil's structure. Through the direct shear box tests, the degree of damage of the adhesive material in the soil appeared different phenomena.…”

“…Hence, considering the importance of the shear strength from the aspect of the safety of construction, an improvement strategy is required to be proposed. Previous studies suggest that the shear stress performance (shear strength) of the soil can be altered by changing the micro-structure of the soil, where several methods, including soil consolidation, soil shrinkage, and soil compaction, can be utilised as promotion approaches (see in Figure 3) [6]. [7] To identify the associated effects in these methods comprehensively, the shear strength investigations towards kaolin clay are required to be conducted respectively.…”

“…An investigation towards a volcanic soil on its shear behaviour has been completed by Avsar et al in 2005 [6], together with the impacts from the micro-structure on this behaviour. Results suggest that two different types of shear strength behaviour had emerged in the direct shear box test, representing that the parameters of shear strength in this soil with a comparatively lower normal stress range surpass those from high normal stress.…”

Shear stress performance has been considered as a significant feature of the soil properties, for it is a major cause of construction failure. The collapse of the building occurs when the stress applied on the soil exceed the shear strength (shear stress performance) of the soil. As a key component of the Brisbane soil, which has been utilised widely as the base soil material in a construction project located in Port of Brisbane, the kaolin clay, however, has attracted special attention due to its high proportion in the Brisbane soil. This thesis intends to mitigate the possible construction failure risk due to shear strength by proffering a legitimate method to improve the shear strength of the kaolin clay. The study investigates the shear stress performance of the kaolin clay mixed with salt solution processed by compaction method, the result of which, will be further compared with the shear strength outcomes of the kaolin clay possessed by other three methods (the shrinkage, the consolidation, and the compaction with soil mixed with fresh water) which were generated by Direct Shear Test. Results suggest that the soil mixed with fresh water processed by the compaction method generates the most satisfying outcome in shear stress performance, which may can be further applied to enhance the construction stability in the Port of Brisbane.

“…Según las características y el historial de erupciones, los depósitos de suelos volcánicos pueden ser estratificados o macizos, de grano grueso o de grano fino, adheridos o no adheridos y fisurados o no fisurados. Dichos materiales cubren áreas planas o con pendiente, alcanzando espesores de hasta varias decenas de metros (Avşar et al, 2015).…”

“…En definitiva, los suelos volcánicos cubren partes importantes de la superficie del mundo, incluidas áreas ocupadas por asentamientos urbanos, estructuras e infraestructuras, y pueden causar problemas de geoingeniería. Algunos suelos volcánicos pueden con frecuencia soportar pendientes casi verticales, cuya ventaja se toma para taludes de carreteras (Avşar et al, 2015). Pero otros suelos volcánicos en regiones tropicales como Hawái (Estados Unidos) tienen los efectos de una meteorización extensa y profunda que puede afectar notablemente las propiedades de ingeniería (Brandes y Nakayama, 2010).…”

The "Soil Nailing" technique is a ground reinforcement procedure used consistently to stabilize slopes and land sections in geotechnical engineering projects. This technique is frequently used in the city of Quito (Ecuador) to reinforce the ground and improve slope stability during the excavation process for various underground parking levels. Such deep excavations are common in the city's most important real estate projects, in which "Soil Nailing" is used with different variations that are adjusted in accordance with the construction resources available in the particular environment. Despite its widespread use, this technique which has proven to be so effective in stabilizing excavations during the construction of underground structures in the soils of the city of Quito, currently suffers from a lack of local theoretical, numerical or experimental research based on the geotechnical properties of the city's characteristic soils.
