abstract: In recent years, engineering has significantly increased the use of numerical modeling, mainly applied in studies solutions and analysis behavior soil - structure foundation element interaction. this sense, paper analyzes blocks foundations made up one, two, three four piles with 25 cm diameter (d) 5 m length (L) unusual spacing between piles, equal to 5d a three-dimensional finite mo...

In this paper, the influence of foundation configuration (raft or separate footings) on tunnel–soil–framed building interaction is investigated using geotechnical centrifuge testing. Tunnelling-induced soil movements and deformation fields, framed displacements structure shear distortions (with associated modification factors) are illustrated. Framed stiffness footing bearing capacity also eval...

In order to compare and analyze the seismic response characteristics of a safety-related nuclear structure on non-rock site in condition raft pile group foundations under unidirectional multidirectional motion input, large-scale shaking table test soil-nuclear system was carried out this paper. test, soil uniform silted clay, shear wave velocity 213 m/s. Considering similarity superstructure na...

در بخش نخست این تحقیق، سطح پلی وینیل الکل (pva) با کوپلیمریزاسیون پیوندی از طریق فرایند انتقال زنجیر برگشت پذیر افزایشی-تجزیه اصلاح شده است. گروه های هیدروکسیل پلی وینیل الکل در دو مرحله مجزا ابتدا توسط برهمکنش با یک ترکیب آسیل کلراید به pva-cl تبدیل و سپس از طریق برهمکنش با 1-برمو نفتالن در حضور کربن دی سولفید توسط واکنش گرینیارد به یک عامل raft بر پایه پلی وینیل الکل تبدیل شد. در انتها پلیمری...
