geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

非圧密非排水（UU）三軸圧縮試験（以下，UU 三軸圧縮試験）や土の繰り返し非排水三軸圧縮試験（以下，液状化強度試験）は，各種サンプラーで採取した土質試料から必要な供試体数を作製する。これらの供試体は，異なる深度で作製されるが均質性があると見做される（以下，現行法）。しかし，著者らは，この見做し事項が供試体の不均質性に繋がり，試験結果に影響を与えると考えた。また，これらの試験結果が設計で採用されないことが多くある。そこで，供試体の不均質性を改善するため口径を拡大した三重管サンプラーによる土質試料から，同一深度の供試体を用いた土質試験を提案する（以下，提案法）。実証実験として，現行法と提案法の盛土のUU 三軸圧縮試験の比較，提案法の沖積砂質土および盛土の砂質土の液状化強度試験を実施した。これらの結果から，提案法は現行法を改善できることが確認できたので報告する。

Granular sands are characterized and modeled here by explicitly exploiting the discretecontinuum duality of granular matter. Grain-scale kinematics, obtained by shearing a sample under triaxial compression, are coupled with a recently proposed multiscale computational framework to model the behavior of the material without resorting to phenomenological evolution (hardening) laws. By doing this,...

We develop a model of distributed damage in brittle materials deforming in triaxial compression based on the explicit construction of special microstructures obtained by recursive faulting. The model aims to predict the effective or macroscopic behavior of the material from its elastic and fracture properties; and to predict the microstructures underlying the microscopic behavior. The model acc...

The use of recycled aggregates to produce precast concrete products is conductive the green development construction industrialization. This paper aimed study effects curing regimes and confining pressures on triaxial compression behavior aggregate (RAC). Triaxial tests were carried out RAC under different (standard curing, 60 °C—12 h 80 °C—9 h), designed 0 MPa, 2.5 5 10 MPa. results show that ...
