The objective of this research was to improve the bearing capacity soil located on Kampung Juhut Street, Pandeglang Regency, which initially had a 3.01%, through stabilization methods. plastic powder selected as an additive due its non-cohesive characteristics, counterbalance cohesive nature clay soil. study aimed identify type and classification, evaluate impact physical properties, examine ch...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

Abstract As more engineering projects and activities are taking place on around weak rocks, it is becoming important to study characterize them. Since regular practices of rock mechanical testing not effective for special laboratory tests measurements were performed the Alkharj Saudi sandstone which a clastic dominantly sandy limestone sandstone. Test results presented in this paper. Porosity, ...

The stability of loess subgrade is affected by many factors. Freeze-thaw cycles are a common factor that causes the strength subgrades to be damaged. In order study influence freezethaw on subgrades, reveal mechanism freeze-thaw subgrades. It necessary sample soil samples in this area, and perform compaction test, cycle unconfined compression test electron microscope scanning analyze microstruc...

Freeze–thaw cycles under the conditions of snowmelt and rainfall infiltration in winter are triggers for petroglyph weathering. Rock samples from Helan Mountains were subjected freeze–thaw various laboratory testing, mass, elastic wave velocity unconfined compressive strength tested. The results show that mass loss rate, decreased. In addition, according to XRD analyses, content calcite feldspa...

A ground-water flow and transport model simulating contaminant movement to public supply wells in the High Plains aquifer near York, Nebraska was developed as part of the U.S. Geological Survey National Water-Quality Assessment Program. Water-quality samples were collected from wells screened in unconfined and confined units. Samples collected from a public supply well and selected monitoring w...
