By controlling the particle size distribution of an Italian silt, influence grading on its behaviour was investigated. As clay content reduced, changed from a typical mode to transitional form between that clays and sands had previously been seen only for gap-graded soils, emphasising this type is possibly much more extensive than thought. The work has highlighted several features behaviour, in particular unique normal compression critical state lines do not exist, Rendulic's principle does...
The behaviour of natural and artificial slopes is controlled by their thermo-hydro-mechanical conditions soil–vegetation–atmosphere interaction. Porewater pressure changes within a slope related to variable meteorological settings have been shown be able induce soil erosion, shrinkage–swelling cracking, thus leading an overall decrease the available strength with depth and, ultimately, progressive collapse. In terms numerical modelling, stability analysis partially saturated complex problem...
An analysis was made of an extensive series oedometer and triaxial tests on intact samples silts silty clays from the lagoon Venice, as well a more limited carefully controlled reconstituted specimens. The soils appear to have transitional modes behaviour with compression curves that converge only slowly in v–log [Formula: see text] plane critical state lines defined for are non-unique v–ln p′ plane. Two means quantifying degree introduced, one factor, m, being based data second, P, data....
To investigate the hydraulic behaviour of fine-grained embankments along mid-course Po River, research was carried out on a full-scale physical model, built floodplain existing embankment and forming pond. The pond filled to reproduce historical floods. prototype according recommendations formulated by River Management Authority. engineering properties foundation soils were investigated in situ tests complemented some suction-controlled laboratory tests.

The weathering degree of the building materials and natural stones is generally quantified as decrement some mechanical features that can be measured experimentally by means compressive tests or point load in laboratory Schmidt hammer carried out situ. Such destructive damaging are unacceptable case cultural heritage since even small amounts damage must avoided. This work shows a correlation between rebound values reflectivity detected terrestrial scanner laser; therefore it allows assessing...
The compression and shearing behaviour in mixtures of soils different granulometries and/or mineralogies has been researched extensively. focus the research to identify key factors that might lead change from transitional not transitional, where is characterised by non-convergent paths critical state lines be non-unique. A review revealed a complex pattern behaviour, which can caused relatively small changes proportion or nature soil particles. It was then assumed mineralogy matrix composed...
The compression in gap-graded mixtures of sands with combined mineralogy has been investigated recent research, focusing on the key factors that might imply occurrence convergent or non-convergent paths (i.e., transitional non-transitional behaviour). From previous work, a matrix composed larger grains seems to determine possibility behaviour. Hence, if there is strong and stiff made quartz sand particles, which are either than at least similar size other component, then behaviour) likely...
A comprehensive series of tests was performed to investigate the effects in-situ structure and sample preparation technique on compression behaviour a shallow young alluvial silty soil. Two different particle size distributions were investigated by testing intact, compacted, slurry samples in an oedometer. The samples, created at initial water contents, gave unique intrinsic line for one two distributions. This used as reference analysing compacted intact specimens. prepared means static...
A recent increase in frequency and severity of exceptional climatic events is concern for the stability natural artificial slopes. These undergo continuous evaporation infiltration cycles, which change suction distribution trigger shrinkage, swelling, cracking, surficial erosion, overall decreasing soil strength. To assess impact these stresses, determination water retention properties a priority. Although advanced techniques have been proposed last few decades to this end, simpler...
When oven-dried powdered clays are heavily compressed they acquire tensile strength, which is variously attributed to bonding or suctions in water not evaporated during oven drying. coarse-grained soils the grains fracture (Coop, 1990; McDowell & Bolton, 1998). The tests described here show that, after compression under stresses of order 100 MPa, carbonate sand develops and compressive strengths 1 MPa due relatively large small quantities released from within pores material. Tests were...
When evaluating the shear strength of rock mass discontinuities, certain challenges arise due to difficulty in quantifying roughness characteristics surfaces and asperities. Recent research has focused on enhancing techniques for assessing these exploring application laser scanning aid discontinuity features. The analysis reflectivity values (I) obtained through a scanner survey presents an efficient method mechanical characteristics, such as joint compressive (JCS). Reflectivity...
The adoption of flowable mixtures treated soils is suggested as a sustainable solution for repairing the damage caused by burrowing animals in Po River embankments. Soil from damaged sites proposed to be mixed with lime or cement, other additives, and water order obtain an adequate compromise between viscosity—which crucial flowing mixture into hole site machines—and shrinkage that might occur over time according boundary conditions. Injections soil-treated must guarantee hydraulic...
This study characterises the effects of naturally varying organic content on compression and shear behaviour a marine silty-clay from Netherlands. Index properties mechanical are determined through laboratory tests, including oedometer multistage loading-unloading triaxial stress paths. The results indicate significant impact response, with both loading reloading indexes increasing as loss ignition increases 3% to 7%. Additionally, suggests directional response behaviour, index ratio....
Animal burrowing along riverbanks has a negative impact on the hydraulic performance, and can have severe consequences structural integrity, of levees. Hence, as soon burrows are detected during monitoring activities, it is strongly recommended that interventions taken within shortest possible time to mitigate disaster risk. The two most common engineering used repair embankments (i.e., excavation area with following backfill or injection low pressure flowable grout) may cause disadvantages...
The sacral complex of the Valle dei Templi in Agrigento, belonging to UNESCO Heritage Site List, stands over crest a stiff calcarenite bench, which overlies layer partially saturated carbonate sand. retrogression slopes and toppling phenomena that have occurred past, caused by undermining combined with discontinuity pattern, threaten some more relevant archaeological structures. Recent studies identified an open metastable structure, typical collapsible soils, for sand under bench. In sandy...
