Research on Mechanical Characteristics of Slope Reinforcement by Spatial Arc Crown Beam Composite Supporting Structure

چکیده
To effectively optimize the mechanical behavior of a traditional anti-slide pile and reduce environmental destruction, new method for slope reinforcement by spatial arc crown beam composite supporting structure was proposed. First, numerical model validated through lab-scale test data obtained herein, then full-scale created an in-depth understanding distribution regularity displacement along pile, soil pressure, stiffness, so on. The results demonstrated that: (1) is simplified to two-hinged arch, maximum value bending moment in about one-third straight theoretical calculation. (2) redistributes load sharing among different piles, extreme other piles varies within 10% downhill direction except at foot. (3) Bending moments are close zero end, can be as vertical with one end fixed hinged. (4) axial force always presented make full utilization compression resistance concrete. (5) characteristic pressure front arch foot from that positions, stable provides greater anti-piles. (6) As stiffness above five times reference value, tends stable, increases continually, My −1013.13 kN·m, constraining effect gradually weakened.

Reinforcement Effect on Mechanical Properties of Bio-fiber Composite
Influence of reinforcement effect on mechanical properties of banana bio fiber polyester has been investigated. Three different type of weaving patterns such as plain, basket and twill banana fabric were used to analyze the mechanical properties of composites. Results revealed that composite with basket weaving style enhances the properties of composite material compared to other two patterns. ...

This study, investigates the effect of bias voltage on structural changes of diamond-like carbon thin film created by ion beam deposition is investigated. For this purpose, the bias voltage in the values of 0 V, -50 V, -100 V and -150 V on the AA5083 aluminum alloy was considered. Raman spectroscopy was used to evaluate structural. Influence of the bias voltage on the thickness and roughness of...
