Root system of vegetation can improve slope stability through changing in mechanical and hydrological properties of root-soil matrix. In this paper, the typical models to describe the mechanical effect in soil-root system and some theories of numerical simulation on root reinforcement mechanism are briefly elucidated, Based on the Strength Reduction Method(SRM) and ABAQUS code, a numerical model is...
Sand is generally considered to be cohesionless material, but there is small cohesion for sand with certain moisture content. It is reasonable to consider the cohesion when analyzing the stability of side slope of high sand embankment. In this paper, direct shear tests of the Shuhe River sand (in Shandong province, China) were done at different moisture contents and dry densities, and a multiple regression...
Wind is strong at the site of Jing River Bridge, the effect of wind load and other possible loadings on the stability of the structure is considered. Based on the actual construction stage, this paper mainly analyzed the nonlinear stability of No.6 and No.7 piers of the Jing River Bridge. Material nonlinearity and geometric nonlinearity are both included in the numerical investigation. The results...
Phenomenons such as ??swell?? exist in storing and transporting of packagings of air conditioners, which affect the safety of the packaging stacks and the product image. According to this, researches were taken out on aspects affecting the resistance capacity of boxes such as environment, material of boxes, and box structure design. By combining method of both design and experiments, we tested the...
Strength reduction FEM is one of the main methods to analyze slope stability. Based on the extended Drucker-Prager yield criterion in ABAQUS, the plastic zone along a sliding surface from slope toe to the top is assumed as the flag to tell the slope sliding. And a typical soil slope stability is analyzed with extended Drucker-Prager yield criterion with different section circle of Mohr-Coulomb yield...
This paper presents a structural health monitoring system for monitoring, with reduced visual impact, one historical building structure. The system is based on fiber Bragg gratings and comprises 19 displacement sensors and 5 temperature sensors. All the sensors were custom made according to the monitoring points' characteristics. The results obtained over the first year of monitoring are presented...
