Abstract
Crossing-road pipelines account for a large proportion in the long-distance pipelines. One of the main live loads pressing underground pipelines is the traffic load. With the rapid development of economy and transportation industry, the tragic load causes increasing problems, such as the failure and damage of underground pipelines. In view of this, the mechanics of undergxound pipes under traffic load were analyzed and simulated. In this paper, by selecting proper material constitutive relation, the contact parameters and vehicle load model, the finite element model of underground gas pipeline was established and the finite ele- ment was analyzed. By using numerical simulation and numerical examples of verification, all the factors which may cause failure of pipelines were analyzed.关键词
