The most important aspect of every civil engineering project is acquiring reliable information on the ground which will be constructed. This research includes a site investigation, seen as primary stage in gathering geological, geotechnical, and other essential data for structures’ safe cost-effective design. Five boreholes at well-spaced spots were drilled subsurface investigation maximum dept...

عملیات تزریق، یکی از راههای کاهش نشت و افزایش مقاومت و تحکیم سنگ درزه دار در ساختگاه هاست. یکی از مسایل پیش رو در این عملیات، برآورد شعاع نفوذ و حجم دوغاب سیمانی است که به عنوان پارامترهای اصلی فرآیند تزریق معرفی شده اند. برای تخمین این پارامترها از مدل های تحلیلی و عددی استفاده گردید. در روش تحلیلی 7 مدل بررسی شد. در مدل سازی عددی بوسیله ی نرم افزار udec نیز مقطع بلوک سنگی، گمانه و درزه ی تزری...
Although a significant portion of conditions encountered in geotechnical engineering, for investigating engineering behavior of soil, involves unsaturated soils; the traditional analysis and design approach has been to assume the limiting conditions of soils being either completely dry or completely saturated. In unsaturated soils the capillary force produce attractive forces between particles....
The occurrence of hazard events in geotechnical practice is often associated with geotechnical uncertainties. To prevent hazard events from happening or reduce the impacts of their consequence, sources of geotechnical uncertainties need to be identified and treated, and appropriate control measure has to be implemented throughout a project. The probabilistic methods are the devices dealing with...
