摘要

对于不同类型的开挖，钻爆法仍然是最经济、最有效的方法。然而，在埋地输送管道附近，振动必须控制在推荐值以下。在三个不同的工程中描述了爆炸引起的地面振动对埋地管道的影响。在第一个项目中，输油管道部分打开，可以直接对其进行大量测量。本文仅对振动监测数据进行分析，建立了地面振动与管道振动的相关方程。这样的方程被用来预测管道上的振动，在直接测量是不可能的。关键词:爆破诱发振动，延时装药量，输油管

Influence of blast-induced ground vibrations on buried transmission pipelines

Drill and blast method is still most economical and efficient practice for different types of excavation. However, in vicinity of buried transmission pipelines, the vibrations must be held below recommended values. Influence of blast induced ground vibrations on buried pipelines has been described throughout three different projects. During the first project, oil pipeline has been partially open allowing extensive measurements directly on it. In this paper, only vibration monitoring data were analyzed and correlation equation between ground vibration and vibration on pipeline has been developed. Such equation is than used to predict vibration on the pipeline where direct measurements were not possible. Keywords—blast-induced vibrations, charge weight per delay, transmission pipelines
