中文摘要八十年代初我们开始对泥石流地声(振动)特征值与泥石流活动关系进行了研究,研制成功“泥石流地声警报器”等,并先后在蒋家沟和长江上游三省六个站点安装使用了8套仪器,其中有5套“AJ-2A地声遥测警报器”在5个预警报站安装使用,其中宁南县城后山史家沟1991年成功监测5场泥石流,并发出预报警。使观测人员能及时进入观测现场,收集各种泥石流资料并随时监视着泥石流的发展趋势,一旦泥石流进一步发展可能给当地人民生命财产造成危害时就能及时发生报警。通过上述成功监测实例又一次证明“泥石流地声警报器”进行泥石流防灾防警是可行的。本文还就“泥石流地声警报器”的报警工作原理和性能特点进行了论述。
英文摘要Debris Flow Ground Sound Warning (DFGSW for short)has already developed into one of the considerably successful methods since 1980's. The vibration wave, just same to other vibration wave, owns its special vibration frequency and waveform from motion, collision of debris flow. NJ-2 DFGSW Device. Based on both the direct ratio relationship between ground sound intensity (amplitude) with debris flow discharge measured at Jiangjia Gully, and the analytical result of characteristic values (frequency, aptitude, lasting time) of debris flow passing section, came into appear. As a new method, this device has quite succeeded in the warning experiment and made great progress at the same time. However, unstable performaxce, limited debugging range of the experiment-warning appliance will help the wrong warning send out easily. As a satisfactory result, DFGSW has been effectively improved during the several years' testing with the Yangtze River Control Project's conducting .These devices have been set up at 5 stations in 3 provinces for debris-flow-landslide-monitoring system in the Yangtze River Upper reaches and all of them have exerted their capabilities. Successfully, all of the debris flows, occurred at shijia Gully behind Ningnan County city back-mountain in 1991, have been accurately warned, and all the parameters describing those debris flows have also been intoduced by listing, such as occurring time, property, maximum, discharge, velocity, and so on. The successful warning test indicates that it is available to warn debris flow by ground sound warning approach, and the improvement of NJ-2 DFGSW device is also effective. These achievements improve the warning capability and enhance the warning frofits of society, economy and hazards-mitigation.
