摘　　要：过去乃至目前，对石油井架的结构力学特性试验，国内许多用户仍普遍采用静力试验方法。现文根据井架结构静力与动力的实测结果和试验方法的分析比较，从井架结构实际承受动载荷的观点出发，论述了结构动力学能够从本质上正确反映载荷与结构之间的相互关系，能够解释许多静力学解释不了的问题。在电子测量仪器、计算机数据处理等技术已相当发展的今天，开展动力试验并逐渐以动力法取代静力法来进行井架结构的力学性能试验是可行的，也是必要的。Abstract Many domestic production units have been using static test method as structural mechanics performance test of derrick from the past till these days. According to the analysis and comparison between actual survey results and test methods of derrick structure dynamics and static, this article expoumds that structural dynamics can reflect the relationship between load and structure correctly and essentially a viewpoint of actual dynamic load borne by derrick structure. This article also explains a lot of problems which static can't solve. Today electronic surveying instrument, and the technology of computer data processing have developed a lot, it is feasible and necessary to carry out dynamic test and gradually conduct a structural mechanics performance test of derrick with dynamic method instead of static method.
