RISInfluence of water and sand content on adhesion of clayey soils
Clogging occurs during mechanical tunneling with a Tunnel Boring Machine (TBM) because of adhesion of clayey soils to the cutter head and conveyor system. The present study examined the effects of water and sand contents ...
طراحی و ساخت دستگاه اندازه‌گیری چسبناکی خاک رسی به سطح فلز و بررسی تکرارپذیری نتایج آن
کلاگینگ (Clogging)یا انسداد یکی از مشکلاتی است که در حفاری تونل با دستگاه TBMبه دلیل چسبیدن زمین‌های رسی به پیشانی برشی و ابزار تخلیه دستگاه‌ها در سطوح مختلف رخ می دهدمرور طرحهای ارزیابی ارائه شده و ابزار ابداعی به کار ...
Adhesion of clay to metal surface; Normal and tangential measurement
Adhesion in geotechnical engineering is the interaction between cohesive soil and a solid surface which can cause clogging in mechanized tunnelling through clayey formations. Normal piston pull out and modified direct shear ...
Assessment of the adhesion potential of kaolinite and montmorillonite using a pull-out test device
The tendency of clay particles to stick other surfaces means it is adhesive and can cause clogging of tunnel boring machines. Clogging arising from adhesion hinders or halts tunneling operations. The nature of adhesion in ...
Experimental and laboratory assessment of clogging potential based on adhesion
Mechanized tunneling through clayey formations is threatened to encounter the clogging problem. Adhesion stress as the tendency between clay and a metal surface leads to clogging between TBM and excavated materials. Some ...
Estimation of the rock mass deformation modulus using a rock classification system
It is often difficult to directly obtain specific design parameters of interest. In these situations, estimation based on empirical correlations is an alternative. The deformation modulus of a rock mass, which is important ...
