No wonder, once a fire arises, we can do nothing to put it under control hut let it go as it is and bring economic lost, injuries and even death to the people. For this reason, work must be intensified on both sides, e. i. design and operational management.Design must be made after the specifications as laid down in the Code...

5 cases of oil storage fire are cited in the article as an example to show the different reasons and lessons, as well as the many unsafety factors still existing in our management. No wonder, once a fire arises, we can do nothing to put it under control hut let it go as it is and bring economic lost, injuries and even death to the people. For this reason, work must be intensified on both sides, e. i. design and operational management.Design must be made after the specifications as laid down in the Code for Design of Oil Storage. Remedy measures should he taken against any possible dangers for former utilitives in oil storage, the fire preventive space between oil storage and nearby buildings, any of which are not in accordance to the code requirement. On the other hand, operaters must be technically trained and those unqualified are not allowed to be on post; anyone should observe the rules and regulations of operation; fire fighters should be ready and on guard all the time, and fire equipment maintained and put into use periodically. These are all for the same aim, safety.

文中例举了石油库5例不同原因而造成油品溢流。油罐爆炸引起的火灾事故,指出在管理上还存在很多不安全因素,一旦发生事故就无力控制而致使扩大,会造成经济损失和人身伤亡。因此,必须加强设计及操作管理两方面的工作。 设计工作必须按《石油库设计规范》有关规定执行,原有罐区的设施、罐区与邻近建筑物的防火间距等,凡不符合规范的要求,都应采取补救措施,防患未然。操作管理方面,必须加强对操作人员的技术培训,不合格者不准上班顶岗;其次必须按操作规程进行操作;消防设备不完善的应及时增设,消防人员应经常操作演习,消防设备要定期维护、试运。其目的是确保油库的安全。

An experimental method for studying dynamic fracture under stress wave loading is described.

An accurate measurement of dynamic crack-opening displacement as a function of time was made using an optical method based on Moire-Fringe. According to the strain gages records...

An experimental method for studying dynamic fracture under stress wave loading is described. On the equipment of Split Hopkinson pressure Bar driven by a fire gun, a tubular specimen with two symmetric through precracks were fractured under axisymmetric impact loading, the loading rate K_I being approximately 10~7 Kg·mm~(3/2)·S~(-1). An accurate measurement of dynamic crack-opening displacement as a function of time was made using an optical method based on Moire-Fringe. According to the strain gages records of incident, reflected and transmitted stress pulses, the average stress applied on the crack site can be estimated as a function of time. From the data the critical value of the fracture parameter can be obtained.

本文描述了一个研究材料动态断裂特性的实验方法.该方法采用霍布金森压杆装置,以火药枪为动力,在加载率K_I大于10~7kg·mm~(-3/2)·S~(-1)条件下将带有穿透裂纹的管状试件冲击拉断.实验中,运用云纹原理,通过一套光学装置,用瞬态变换器记录裂纹张开位移随时间的变化.用粘贴在试件上不同位置的应变片,通过超动态应变仪,用瞬态变换器记录入射、反映和透射应力波.由此确定作用于裂纹面的载荷随时间的变化。由反射应力波记录到的裂纹起裂时产生的卸载扰动讯号和裂纹张开速率的急骤转折点来确定起裂点. 本方法与目前广泛采用的示波摆锤冲击法相比,加载速率提高了近两个数量级,更能适应动态破坏的需要.而且力学分析基础也较摆锤冲击法更可靠.采用上述测量和记录系统,采样时间为0.2μs,断裂全过程约36μs,可得180个数据点,为对断裂各阶段进行分析提供了可能.
