Design of Blasting Scheme Based on Numerical Simulation

Abstract:

Operating safety of adjacent pre-constructed pipeline must be insured when the crude oil and refined oil pipeline is under construction. Applying finite element method, the peak velocities of observed points located at test segment and operating segment of West to East Gas Transmission Pipeline were calculated, and the ratio of the two peak velocities in different relative positions was also obtained. Taking advantage of quantitative relationship between the detonation charge and vibration velocity of particle on the pipeline, the ratio of detonation charge is derived from the peak velocity ratio, thereby the blasting scheme of West to East Gas Transmission Pipeline with different thickness is ascertained. This method is not only economical and convenient, but also has no damage to the pipeline, which also works for other blast schemes of different conditions.
