the main objective of this study is to swing krull intersection theorem in primary decomposition of rings and modules to the primary decomposition of soft rings and soft modules. to fulfill this aim several notions like soft prime ideals, soft maximal ideals, soft primary ideals, and soft radical ideals are introduced for a soft ring over a given unitary commutative ring. consequently, the p...

Road and subway tunnels in soft clay soils subjected to traffic loading often cause lager settlement. It can pose danger the surrounding buildings structures. Hence, it is necessary for engineers correctly predict long-term deformation of saturated foundations under cyclic loading. In this paper, a series dynamic triaxial tests were carried out on Nanning investigate effect frequency stress axi...

To study the influence of sand particles on strength and dry–wet cycle characteristics cement-solidified South China coastal soft clay, a series clay samples with different contents sizes were prepared, unconfined compression (UCS) tests, tests under seawater freshwater conditions, scanning electron microscopy X-ray diffraction carried out. The test results show that UCS cement–sand-solidified ...

Polymer microstructures are incorporated in biomicroelectromechanical system (BioMEMS) devices with applications ranging from drug creening to defense applications. Nanomechanical characterization of the polymer components must be carried out in order to design reliable evices. This paper presents the nanoindentation characterization of polymer beams fabricated through soft lithography-based te...

this paper presents the numerical analysis of seismic soil-pile-superstructure interaction in soft clay using free-field soil analysis and beam on winkler foundation approach. this model is developed to compute the nonlinear response of single piles under seismic loads, based on one-dimensional finite element formulation. the parameters of the proposed model are calibrated by fitting the experi...

Nuclear magnetic resonance (NMR) can help to collect soft clay pore size data. This paper uses NMR study the effect of freezing duration, gap time between two actions and thawing temperature on distribution (PSD) in clay. It was found that most progress completed during first hours. A longer second cycles leads greater structural damage. An appropriate results less subsidence induced by artific...

In order to study the influence of saturated characteristics soft clay on unconfined compressive strength, Guangdong-Hong Kong-Macao Bay Area is taken as research object, comparing and contrasting compression test unsaturated in laboratory, studying variation law strength sensitivity clay. The results show that: 1. During failure samples, oblique fractures appear, showing brittle shear failure,...
