摘要:
为研究中硬岩管沟爆破时10~20 m范围内既有并行管道所受到的影响，进行现场爆破试验,并采用ANSYS/LS-DYNA数值模拟软件来研究既有管道的地表质点振速峰值和管沟成型效果，得出适用于中硬岩地段管沟开挖的爆破参数，并分析了既有管道迎爆面和背爆面的振动响应。研究表明：管沟爆破试验的振速均能保证既有管道的安全，试验2#的爆破参数更适合中硬岩岩石；垂直地表方向（Y方向）的质点振速峰值最大，且振动速度随着爆心距的增大呈非线性减小；既有管道在迎爆面受到的扰动大于背爆面，迎爆面Y方向的应力、振速均最大。
Abstract:
In order to study the influence of pipe trench blasting on the parallel pipeline with a distance of 10-20 m, field blasting test was conducted and ANSYS/LS-DYNA numerical simulation software was used to study the peak vibration velocity of the existing pipeline and the forming effect of the tube groove. Appropriate blasting parameters were obtained to be applied in the excavation of medium hard rock, and the vibration response of the pipeline was analyzed by numerical simulation. Results show that vibration velocity in blasting test can ensure the safety of the existing pipeline, and the blasting parameters of Test 2# are more suitable for the medium hard rock. The maximum peak vibration velocity is in the direction of vertical surface (Y direction), and vibration velocity decreases linearly with the increase of distance. Disturbance at attack surface of the existing pipeline is greater than that at the backplane, and the stress and speed in Y direction at attack surface are the largest.
