Research on the Stability of Anti-Slip Pile Support Structures for Railway Pile Slopes
نویسندگان
چکیده
The accumulation slope is widely distributed in the mountainous area of China; this paper takes Chengdu–Lanzhou Railway as engineering background and analyzes stability mechanical properties anti-slip pile under symmetrical train loads. First, finite element software Midas GTS NX was used to analyze effect after support at different spacings, row distances, positions. Then, analysis results pile-side earth pressure landslide thrust were compared with those theory, standard method, field-measured data. are follows: (1) increased coefficient from 1.175 1.680. (2) gradually decreased increases spacing distance rose first then an increase position. (3) active values behind by Coulomb theory slightly smaller than result; theoretical passive before much larger results. (4) calculated transfer method when safety factor K = 1.00. explicit implicit same, which 8–19% higher simulation value; 1.35, value about three times simulated value, 2.3 value. (5) measured verified that had a certain degree reliability, relative deviation between two 5–17%.

Seismic Bearing Capacity of Strip Footings on Pile-Stabilized Slopes
This paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. The resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. This comparison indicates an acceptable agreement. The variants of the study incl...

متن کاملMorphological clues to wet granular pile stability.
When a granular material such as sand is mixed with a certain amount of liquid, the surface tension of the latter bestows considerable stiffness to the material, which enables, for example, sand castles to be sculpted. The geometry of the liquid interface within the granular pile is of extraordinary complexity and strongly varies with the liquid content. Surprisingly, the mechanical properties ...
متن کاملThe Effect of a Transient Dynamic Loaded Pile on a Neihbouring Pile for Nonhomogeneous Soils
ABSTRACT This study presents an investigation of the interaction effect of one loaded pile on a neighboring pile under transient dynamic loadings. Analyses are carried for non homogeneous soils. The hybrid boundary element formulation is used to represent boundary integral representation of soil domain and pile equations represented by linear structural components. The formulation is presented ...
