Abstract

Nowadays, duo to mining and construction activities' progression, the need to utilize blasting has been increasing in order to reduce time and cost. The use of blast for drilling and crushing rock, in addition to its advantages, has disadvantages, the most important of which is ground vibration. Vibration caused by the blast is an important and significant part of the blast process and controling its amount in order to reduce possible damage to the surrounding areas, is always necessary. In this paper, the field data of the blast in the second line of the Tabriz water pipeline project have been collected using three-component Blast Recorder seismographs. By modeling the process of blast in ANSYS-Autodyn finite element software, the behavior of the blast zone environment is simulated. The average of numerical modeling errors compared to field surveys is estimated at about 20%. According to the numerical modeling, the most critical state of velocity entering the pipeline is less than the allowable blast standards near the pipeline, and the maximum stress, strain, and displacement in the boundary of pipe and soil are equal to 17.24 MPa, 135 μmm /mm, and 0.18 mm, respectively.
