Affected by climatic conditions such as rainfall, evaporation and air temperature, most of the backfill soil is in an unsaturated state, decrease matric suction leads to failure retaining structure. In view this, this study takes vertical rigid wall with narrow research object, assuming that behind forms a circular arch considering interlayer shear stress; thus, analytical solution active earth...

Considering the limitations of terrain and engineering expenses, antislide piles are sometimes arranged in polylines. Studies show that this arrangement adversely affects mechanical characteristics piles. However, there is no in-deep understanding issue structural design calculation method have not been discussed relevant standards. Aiming at resolving shortcoming, polylines pile studied articl...

Abstract Precast slab parameters are important factors affecting the mechanical performance and service life of precast-slab-fabricated recyclable roads. To clarify force mechanism roads provide a basis for selecting parameters, field test road fabricated using large-scale precast was conducted in this study. The horizontal vertical stresses on top bottom surfaces determined. stress-time histor...

Stress arching effect during the excavation of broken surrounding rock in underground engineering has an important influence on stability after excavation. To determine stress horizontally layered jointed mass, characteristics mass is analyzed this study by using a series numerical tests. The formation mechanism arch revealed through comparison voussoir beam structure and theoretical analysis m...

The definition of rigid floating piles in engineering applications remains ambiguous. This paper develops a numerical model piled embankments and the modeling method is verified through cases. Utilizing this model, critical bearing capacity foundation for firstly determined to be approximately 150 kPa. Subsequent parametric studies show that soil arching embankment begins occur when ratio heigh...

The various criteria used for graduating the thickness of violin plates are discussed. These are shown apparently to be conflicting. A case is made that the flexural stiffness of the plates should be given priority. A simple indirect method is given for finding the flexural stiffness of the plates without the need to flex them in the hands or to apply forces and measure deflections. The method ...

The field of infrastructure rehabilitation and development requires a better understanding of soil-structure interactions. The interaction behaviour between soil and structures has mostly been investigated through theoretical and/or numerical analysis. This paper presents a series of experiments performed on an intermediate-scale physical model made of an instrumented silo. In contrast to most ...
