###### Abstract
Other scholars have studied the influence of steel large-diameter pipelines on resistance to dynamic disturbance. [PERSON] et al. [17] studied the underground blasting performance of X70 grade steel pipe pipeline, calculated the anti-explosion load performance of pipeline thickness, internal pressure, soil type, carbon fiber cloth thickness, and other factors, and summarized the safety area of underground pipeline against underground explosion load. [PERSON] et al. [18] studied the impact of earthquakes on large-diameter culverts built with corrugated steel plates. It is found that the widely used equation evaluation method significantly underestimates the destructive effect of earthquakes. [PERSON] et al. [19] studied the damage effect of large-diameter corrugated metal pipes against seismic load dynamic waves and summarized the quasi-static analysis method of large-diameter flexible underground pipelines based on ground strain. The evaluation of transient strain and permanent strain of the pipeline can be realized. For the safe operation of pipelines under tunnel blasting vibrations, the key is to ensure that the peak particle velocity (\(PPV\), under the action of seismic waves--the velocity of reciprocating motion of medium particles, generally obtained by blasting vibration sensor and supporting blasting vibration monitor) does not exceed the allowable vibration speed standard. According to the Blasting Safety Regulations (GB6722-2014) [20], the standard for PPV of a hydraulic tunnel under different frequencies is in the range of 7-15 cm/s. By fitting the relationship between the tensile stress and vibration velocity of a structure under tunnel blasting, [PERSON] [21] and [PERSON] [22] proposed a blasting safety vibration control standard for underground structures according to the maximum tensile stress failure criterion. [PERSON] et al. [23] and [PERSON] et al. [24] studied the failure behavior of pipelines with dent defects under the action of nearby explosions, quantified the deformation of pipelines caused by different defect sizes, and obtained a wider function relationship between defect and plastic deformation. [PERSON] [25] proposed a formula to calculate the safe vibration velocity of blasting under different operating pressures based on the maximum shear stress failure criterion. [PERSON] et al. [26] and [PERSON] et al. [27] studied the damage behavior of polyethylene bellows subjected to explosion. Based on intelligent algorithms such as genetic algorithm and particle swarm optimization, the optimal intelligent model of pipeline response characteristics was predicted. The research results provide suggestions for blasting design. In addition, there were many cases of analyzing the failure of surrounding rock under close blasting from the perspective of cumulative damage [28; 29; 30; 31; 32; 33], while there is little research on the cumulative damage and safety evaluation of pipelines under the blasting of a large number of boreholes and continuous initiation of multiple rows of multiple blast holes. In summary, most studies have focused on the vibration response and stress-velocity safety evaluation methods for small-diameter pipelines (usually less than 1 m) under tunnel blasting. However, the research on large-diameter (more than 6 m) pipelines is not yet sufficient. In addition, the effect of close-range blasting on pipelines has been relatively overlooked, as most studies tend to concentrate on the vibration response of pipelines caused by far-field blasting. Moreover, quantitative comparative analyses of the vibration response and cumulative damage of pipelines under different types of simultaneous multi-hole initiation using non-electric detonators and hole-by-hole initiation using electronic detonators have been less studied. Finally, a pipeline safety evaluation standard based on the cumulative damage variable and damage range was not available.
