Finite Element Analysis of the Stability of Tunnel Surrounding Rock with Weak Rock Layer
The evaluation of local stability of the tunnel surrounding rock mass with weak rock layer is very important for the economy and security of the tunnel construction. Based on the rock tunnel geological conditions in the construction, the finite element model of the tunnel surrounding rock mass stability analysis with weak rock layer is established in the article by selecting the ABAQUS program ...
متن کاملTunnel surrounding rock classification forecast based on the geological advanced prediction system in seismic area
The global earthquake disaster happened frequently in recent years, how to guide the construction correctly in seismic area becoming a problem to be solved, while the study on the tunnel geological advanced prediction system in seismic area is limited. This paper established an integrated prediction system which was combined with engineering geology analysis and geophysical method combined with...
متن کاملResearch on Grey System Model and its Application on Displacement Prediction in Tunnel Surrounding Rock
In the process of the highway tunnel construction, the stability and the reliability of tunnel rock is an important guarantee to ensure safety construction. Tunnel surrounding rock deformation monitoring is an important method for obtaining information on surrounding rock and controlling tunnel stability in the period of construction. Forecasting deformation of surrounding rock is the key to es...
متن کاملthe effect of genre-based teaching on reading comprehension of literary texts
تحقیق حاضر به بررسی کاربرد روش ژانر-محور را در محیط آموزش زبان عمومی می پردازد.روش ژانر-محور به زبان آموزان کمک میکند که در زمینه خوانش پیشرفت کنند. بعضی از محققین معتقد اند که روش تدریس ژانر-محور به تدریج به زبان آموزان کمک می کند تا در درک ژانر های مختلف مهارت یابند (هایلند 2004).همچنین امروزه توجه روز افزونی به اهمیت استفاده از ادبیات در برنامه آموزشی زبان انگلیسی (esl/efl ) شده است. زمانی ک...
15 صفحه اولEffects of the Soft Rock Pre-consolidation on Time-dependent Deformations around the Tunnel Excavation
Original scientific paper Time-dependent deformations in soft rocks represent an important part of total deformations which occur after excavation of the tunnel opening. In the light of this, comprehensive laboratory uniaxial creep tests were performed on marl rock monolits. The testing used marl as a chosen representative rock samples of the group of soft rocks which exhibits creep behaviour. ...
