Surface treatments of engineering materials are important for serviceable engineering components. One of the thermo-chemical surface treatments of steel based materials is the boriding process. In this study, low alloy steel substrates were borided by pack boriding process at 900 C. Experimental indentation tests were conducted on Dynamic Ultra-micro Hardness test machine, under applied peak lo...
Due to the complexity of pile–soil interaction, there is little research on active–passive piles that bear pile-top load transmitted from superstructure and pile shaft caused by lateral soil movement around simultaneously. The purpose this study analyze displacement internal force piles. Most design codes in China use elastic resistance method describe relationship between horizontal pile, but ...
High-speed railways are built in deep soft-soil foundations interlayered with hard materials. However, the layers cannot be penetrated by conventional foundation treatment. Moreover, project cost is sometimes prohibitive, which an issue for post-construction subsidence control. The bag grouting pile a special grouting-pile-reinforcement technique treating This paper conducted tests on Ningbo-Ta...
With the development of urban metro systems, shield tunnels that pass through existing bridge pile foundations have become an inevitable engineering problem. Therefore, ensuring stability strata and piles during tunnel construction is a common goal in practice. Currently, research on mechanical responses under different conditions upper-soft lower-hard composite tunneling has not been conducted...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
