Large–scale underground coal mining is bound to cause serious surface subsidence problems. However, conventional filling and methods have problems such as high cost process difficulty. In order achieve the purpose of efficiency low cost, this paper proposes using technology CGSG. To effective control overburden strata movement ground settlement cemented gangue strip in goaf (CGSG), studies desi...

Abstract Concrete-filled steel tube (CFST) columns are widely used in civil engineering because of their excellent bearing capacity; however, the reinforcement CFST lacks effective measures. To strengthen quickly and effectively, two methods, namely, winding FRP (fiber reinforced polymer) or strips, were explored this work. Two unconfined columns, eight FRP-strengthened four welded strip-streng...

A finite element program based on elastic –plastic model of Mohr-Coulomb criterion was used to evaluate the bearing capacity coefficients of soil under shallow strip flexible footing . The results were compared with others’ analytical results and it was found that the present study could offer quite consistent and rather precise values for the bearing capacity coefficients . &#10&#10The effect ...

Marvelous bending/straightening effects of two-way shape memory alloy (TWSMA) help their employment in design and manufacturing of new medical appliances. Constrained ageing with bending load scheme can induce two-way shape memory effect (TWSME). Scanning electron microscope (SEM) analysis, electrical resistivity measurement (ERM) and differential scanning calorimetry (DSC) are employed to dete...

Abstract The goal of the work reported was to determine influence selected shot peening parameters on deflection Almen strip and load capacity single-lap adhesive joints made 2-mm-thick aluminium alloy EN AW-2024-T3. Moreover, research aimed at checking possibility using indicator predict after peening. analysis carried out according Hartley’s PS/DS-P:Ha3 plan. input factors were parameters: tr...

in order to study the effect of strip intercropping of maize (zea mays l.) and bean (phaseolus vulgaris l.) on the dry matter yield and land equivalent ratio (ler) in weedy and weed free treatments, an experiment was conducted at the agricultural station of college of agriculture, ferdowsi university of mashhad, iran. treatments were strip width of 2, 3, 4 and 5 rows and sole cropping of each c...

in this paper, the rolling force and reduction ratio have been investigated in multilayer strip rolling. for this purpose, two different set of multilayers have been selected which are al/st/al and cu/al/cu layouts. at first, the validation of the numerical analysis was performed by using an experimental test. after validation of the numerical results, two set of multilayer layouts were simulat...
