Special element for numerical modelling of the rock bolt reinforcement
Original language description
Rock bolts as construction elements are often used in underground civil engineering projects. This work deals with their mathematical modelling. Finite elements of Aydan type were used for the description of rock bolts and hexahedral quadratic finite elements were used for the description of rock massif. A new code for the computation of stiffness matrices and right hand sides of these elements was developed by us. Stresses in a rock massif around an excavation reinforced by rock bolts were computed using the mentioned code and the solver PMD (noncommercial code developed at the Institute of Thermomechanics AS CR). The results show that the use of rock bolts can reduce the area of the maximal mechanical stress in the vicinity of excavations.
