摘要：The fragments produced by explosion of horizontal tank are destructive, which may lead to the damage of adjacent vessels, and then cause the domino effect. Therefore, it is very important to study the primary and secondary fragments respectively produced by source explosion and target destruction. The possible accident types of industrial horizontal vessels were analyzed, and the number of fragments including tank body and accessories were obtained, with the corresponding accident frequency. Based on the maximum entropy principle, the probability distribution models of the number of primary fragments including tank body and accessories were established. Then, the probability model of the number of secondary fragments was obtained by further deducing the probabilistic formula of the volume of fragments formed by the adjacent facilities under the explosion load. Compared to previous work, the fragments including vessel, its accessories and secondary fragments caused by objective crack were comprehensively explored, with the improved results, which had more practical values and significance and were an effective reference for the layout of chemical plants and accident prevention. ?
