Abstract AR
في هذا البحث استخدمت طريقتا الإسقاط الاستريوجرافي و تحليل المتجهات في دراسة حالات الثبات الصخري على طول مسار النفق المروري المقترح رقم ٣، إذ إن هذا النفق مخطط و مصمم على أن ينشأ في صخور من الاردواز و الثست الكلوريتي المتداخلة بصخور بازلتية.
و تحتوى منطقة الدراسة عل تراكيب جيولوجية منها اثنان من الشقوق الرئيسة و واحد ثانوي بجانب التورق و التصفح و نتيجة لهذه الدراسة، فقد يكون هنالك سقوط حر للصخور من سقف النفق، و كذلك انزلاق من الجدار الشمالي الغريب على طول مسار النفق.
و توصى هذه الدراسة باستخدام نظام مسامير التثبيت لدعم و تثبيت الصخور غير المستقرة.
Abstract EN
TWO methods, namely stereographic projection and vector analysis, have been adopted herein to investigate the stability conditions along the proposed route of traffic tunnel No.
3.
This tunnel is planned to be driven through foliated slate and chlorite-schist intercalated by metabasaltic rock.
The structural features in the studied area are mainly joints of two major and one minor sets, besides the cleavage and schistosity.
The study concluded that free falling from the tunnel roof and sliding of blocks in the north- western sidewall will take place along most of the tunnel length.
Rock bolts are the most suit- able support system for the unstable blocks.
