It is considered to be of value for plastics to replace steel in certain long distance pipelines. According to the importance of stress calculation of burried glass fibre reinforced pipes acted on by external load of soil, and the method of structural mechanics, and guided by the theory of soil engineering, analyzed in this article is the soilpressure destributionmode. The formula of calculating internal stress destribution caused by external load of soil is given as well.The utility and reliability of the formula are proved through practical example calculation.

在某些长输管道中考虑“以塑代钢”是有一定价值的。鉴于埋地玻璃钢管在土壤等外荷载作用下应力计算的重要性,文章按照结构力学方法,结合土壤工程理论,分析了地下玻璃钢管的土压力分布模式,提出了在土壤外荷载作用下的内力分布计算公式,通过实例计算,证明了公式的实用性和可靠性。

The applications of fibreglass reinforced pipes are steadily on the increase in all the advanced industrial countries. U. S. produces fibreglass reinforced plastics with an annual growth rate of 10% ; 25% of the large diameter water pipelines in Japan and 25% of the total length of pipelines in UK a.re fibreglass reinforced pipes. The industry of fibreglass reinforced plastics in China started late and has a slow progress in its application due to the doubt that this new material is more costly. To clear this mind of doubt, market study and economy analysis are made, and the equivalent cost under the same condition compared between fibreglass reinforced pipe and the corrosion protected carbon steel pipe. The comprehensive evaluation, supported by a project budget of a practical case and the data and information provided, concludes that fibreglass reinforced pipe is less costly and has a better serviceability than carbon steel pipe. This conclusion offers a strong evidence for the populization of fibreglass reinforced pipe in China.

当今世界先进的工业国家,应用玻璃钢管的数量与日俱增,美国玻璃钢生产的年增长率为10%,日本大口径供水管道中,玻璃钢管占25%,英国管道总长度中玻璃钢管占25%。我国玻璃钢管工业起步较晚,人们对玻璃钢管的应用怀有疑虑,认为玻璃钢管价格高,影响其广泛使用。为了消除疑虑,进行了市场调查和经济分析,以玻璃钢管和防腐处理后碳素钢管在同等条件下的等效排管费用作比较,列举了工程概算实例,提供了有关数据资料,作出了综合评估,玻璃钢管费用低于碳素钢管,其使用效果也优于碳素钢管。这一结论为玻璃钢管在我国的推广应用,提供了有力的论据。

This paper deals with the theoretical study on the relation of the ratio between shear stress and stretch stress in the direction of channel thickness with the expanding angle of expanding channel die and the channel thickness.The theoretical analysis and experiments have shown that the ratio of the short fibre hoop orientation in pipe wall increases with the increase of the die's expanding angle, and the increasing of channel thickness is to help fairly fast form the hoop orientation.By aforementioned...

This paper deals with the theoretical study on the relation of the ratio between shear stress and stretch stress in the direction of channel thickness with the expanding angle of expanding channel die and the channel thickness.The theoretical analysis and experiments have shown that the ratio of the short fibre hoop orientation in pipe wall increases with the increase of the die's expanding angle, and the increasing of channel thickness is to help fairly fast form the hoop orientation.By aforementioned work, the base therefore can be set up in controlling the short fibre orientation distribution in reinforced pipe by the change of the die's geometric parameter.

本文从理论上研究了剪切与拉伸速率在流道厚度方向上的比率与扩芯式机头扩张角和流道厚度的关系,并从几个方面作了实验工作。理论分析与实验的验证,均证明了随着机头扩张角的增大,胶管中短纤维周向取向的比例增大,而机头流道厚度的增加也有利于周向取向的较快形成。通过上述工作,为从机头口型几何参数来控制增强胶管中的短纤维取向分布建立了基础。
