Abstract In the last decade, biopolymers have been used as organic soil binders in ground improvement and earthen construction material modification. Although biopolymer-treated soils substantially enhanced mechanical strength, deformation characteristics under external loads durability (e.g. biodeterioration due to microbial activity) not yet fully understood, which limits situ practical application of biopolymer-based treatment technology. This study investigated efficiency combined...
This paper presents a new constitutive model for cyclic loading of soil to predict the behavior soft clays under undrained triaxial loading. It is inspired by modified Cam-clay theory, and yield surface elastic unloading proposed capture Only two additional parameters that characterize are used together with traditional associated model. The details relevant properties, initial states, conditions presented, computational procedure determining effective stresses strains demonstrated. simulate...
Sand–clay mixtures can be encountered in both natural soils (e.g., residual soils, clay deposits and clinosols) artificial fills. The method of utilising biopolymers ground improvement for sand–clay has emerged recently. However, a full understanding the strengthening effect biopolymer-treated not yet been achieved due to limited number relevant studies. In this study, xanthan gum (XG), as one eco-friendly biopolymers, was used treat reconstituted that had various compositions related (or...
Planting vegetation is a sustainable and eco-friendly method for shallow slope stabilization. However, in water-limited regions, this facing challenges such as retarded growth, which leads to unprotected soils. Biopolymers, with potentials both growth promotion soil strength enhancement, are therefore tested study regard their possibility assisting reinforcement through cultivation direct shear tests. Both sugar-based protein-based biopolymers improved water availability growing plants...
With the continuous increase in bridge lifespans, rapid check and evaluation of vertical bearing capacity for pile foundations existing bridges have been greater demand. The usual practice is to carry out compression tests under static loads order obtain accurate ratio dynamic stiffness. However, it difficult costly conduct situ experiments each foundation. Herein, a method measure proposed. Firstly, 3D-bearing cap-pile group-soil interaction model was established simulate test foundation...
Abstract Tensile characteristics are the most significant mechanical properties for coated woven fabrics as membrane materials used in lightweight constructions. Factors that might affect test results of material under uni‐ and bi‐axial tensile loads examined. After series tests on PVC‐coated materials, it is demonstrated (1) to measure strains two perpendicular directions, contact method by needle extensometer does not interfere correct data recording; (2) positions where measured specimens...
Pure and routing-algorithm-based connectivities of random radio networks are studied by theoretical analyses computer simulation respectively. The 'magic number' average neighbours each station from connectivity point view is obtained.
Previous studies have revealed that prefabricated vertical drains (PVDs) are effective in stabilizing the soft subgrade soils under traffic-induced cyclic loads. A consolidation model of clays loading incorporating both radial and drainages, nonlinear variation compressibility permeability is presented this paper. The prediction matches well with result from a large-scale triaxial test conducted on soil sample installed single PVD. Parametric analysis has also been carried out to explore...
In the last decade, biopolymers have been extensively studied, showing a great potential in soil reinforcement and promotion of vegetation growth with limited environmental impact. this paper, reinforcing method combined biopolymer (xanthan gum, XG) plants (oat) was proposed to strengthen clayey different pore fluid pH values. A series laboratory tests were conducted, mainly including plant cultivation direct shear tests. It found that oats grew better neutral, weakly acidic, alkaline...
The deterioration of the physical and mechanical properties tonalites subjected to freeze‐thaw cycling under three different temperature ranges was explored using several experimental techniques. Uniaxial compression three‐point bending tests were conducted on untreated treated tonalite specimens. Clear decreases in uniaxial compressive strength (UCS), Young’s modulus, fracture toughness observed specimens with frost damage. Although modulus did not show clear as minimum cycle decreased from...
The multi-pile composite ground with fully penetrated long rigid piles and partially impervious or pervious short is a new type of soft soil improvement technology. Based on the equal vertical strain assumption, governing equations for average excess pore water pressures within surrounding are derived under ramp loading. corresponding analytical solutions developed based one dimensional consolidation theory double-layer ground, overall degree presented. accuracy proposed solution examined by...
