摘　　要：采用力平衡法推导出钢丝缠绕增强塑料复合管常温下短期爆破压力计算公式。开展复合管短期爆破压力试验研究,得到20种型号复合管短期爆破压力试验结果。计算值与实验值相对误差在-11．9％-7．4％内,相对误差平均值为-1．5％。结果表明,所推导的公式具有较高的计算精度,能准确预测钢丝缠绕增强塑料复合管短期爆破压力,用于强度优化设计。Equation for short-time burst pressure of pipes reinforced by cross helically wound wires （PSP） was formulated based on method of force equivalent. Experiment was carried out on the shorttime burst pressure of 20 different specifications of PSP at normal temperature. Comparison between the calculated results with the experimental data showed that the relative errors were within - 11.9 % 7.4 %, and average relative error was - 1.5 %, which indicated the equation proposed can be used in predicting the short-time burst pressure and optimizing design of composite pipes.
