In order to investigate the influence of different diameters on pile end resistance, side axial force and transmission law jacked penetration, two pairs embedded sensitized microfiber grating sensors were installed by slotting body. The pile-jacking process static-pressing viscous foundation soil with closed-tube model piles was successfully monitored. test results show that pressure, resistanc...

Aim of study: Soil compaction causes an increase in bulk density, resistance to penetration, low diffusion oxygen and water the soil. Tillage is one techniques alleviate compaction. The objective this work was evaluate effects tillage on sweet pepper grown greenhouse soil.Area experimental conducted a plastic at Experimental Station University Almería (SE Spain).Material methods: soil ploughed ...

This paper presents 53 well-documented cases of the short-term set-up of open-ended steel pipe piles driven at two fields in the North Sea. Increases in soil resistance during driving (set-up) were observed when pile driving was re-started after delays typically ranging between 24 h and 100 h. The soil encountered at the sites consisted of overconsolidated sands and clays, where the clays varie...

The present study aimed to investigate the spatial variability of soil penetration resistance (SPR) in cultivation areas ‘BRS Princesa’ banana, evaluate its effects on chemical and physical attributes indicate localized management. experiment was carried out an area which 60 georeferenced points were recorded. SPR measured from cone index 0.40 m depth using impact penetrometer. Disturbed sample...

Microwave brightness temperature measurements were made over three different bare soils at frequencies of 5 GHz (X = 6 cm) and 1.67 GHz (X = 18 cm) to compare differences in penetration depth according to texture, soil moisture, and wavelength. The soil plots were wetted, and circularly polarized microwave measurements were made during the dry-down cycle. Soil profile temperature and profile mo...
