Take the cemented soil mixed with the soil polluted by Sodium Hydroxide as object, the relationships between of their electrical resistivity and age, sodium hydroxide content, unconfined compression strength have been studied quantitatively. Then combined with microscopic photos, the change mechanism of electrical resistivity and unconfined compression strength were analyzed. Results show: the electrical...
Take the cemented soil mixed with the soil polluted by vitriol as object, the relationships between of their electrical resistivity and age, Vitriol content, unconfined compression strength have been studied quantitatively. Then combined with microscopic photos, the change mechanism of electrical resistivity were analyzed. Results show: the electrical resistivity are increased with the increase of...
In order to study the impact of pile length on the bearing properties of long-short piles composite foundation, distribution of the axial force and skin friction along pile, the bearing mechanics of long-short-pile composite foundation with long and short piles were studied based on laboratory tests in three different conditions: 60-centimeter-long long piles with 20-centimeter-long short piles, 60-centimeter-long...
We present a novel X-ray frame camera with variable exposure time that is based on double-gated micro-channel plates (MCP). Two MCPs are connected so that their channels form a Chevron-MCP structure, and four parallel micro-strip lines (MSLs) are deposited on each surface of the Chevron-MCP. The MSLs on opposing surfaces of the Chevron-MCP are oriented normal to each other and subjected to high voltage...
