This paper presents a numerical investigation on the improvement mechanism of dynamic compaction (DC) in saturated soil weak layer with high levels groundwater, using an improved fluid–solid coupling method Drucker–Prager–Cap model. The model is verified by comparing published test data at first, which show that dual-phase can approximately reflect development law excess pore water pressure and...

The geogrid-reinforced soil structures play important roles in the reinforcement applications since 1980s. Generally in design of the geogrid-reinforced soil structures, the soil-geogrid interaction behavior is not directly considered. Instead, the interaction strength is represented by the consolidation drained strength of soil commonly. However, neglecting the effect of compaction and suction...

Geosynthetics have become well established construction materials for geotechnical applications in most parts of the world. Because they constitute manufactured materials, new products and applications are developed on a routine basis to provide solutions to routine and critical problems alike. Results from recent research and from monitoring of instrumented structures throughout the years have...

Article considers the case of optimizing design solution for foundation a 10-storey residential building on sandy soils. Optimization was achieved through experimental work with 2*2*0,2 m reinforced concrete slabs and 5000 cm2 stamps. During testing slab settlements, in reinforcement, as well contact pressure under were measured. stamps displacements stamp surrounding soil measured at 21 points...

Vegetation can signiˆcantly contribute to stabilise sloping terrain by reinforcing the soil: this reinforcement depends on the morphological characteristics of the root systems and the tensile strength of single roots. This paper describes an investigation on the reinforcing eŠect of soil-root matrix in the laboratory using a modiˆed large shear box apparatus (300 mm×300 mm). Four diŠerent spec...

The construction of toll roads in South Sumatra faces two problems. First, most the road sections are built on soft soil deposits, so must be improved to speed up consolidation process and improve bearing capacity. Second, embankment required reach design elevation is quite high that reinforcement needed slope stability. This paper contains results a study effect improvement using PVD vacuum pr...

methods are proposed to develop idealized moment-curvature response curves of slender rectangular rc wall sections with uniformly distributed longitudinal reinforcement, using limit states, namely, cracking of concrete in tension, tensile yielding of reinforcement layers, and compression failure of concrete. it is recommended that tensile yielding of an inner layer of reinforcement is considere...
