佛坪县城泥石流危害与防治

Foping County debris flow disaster and its prevention

以位于秦岭山地的陕西佛坪县城为研究对象,对其泥石流灾害及其防治状况进行研究。研究采用地质灾害防治方法,通过野外考察,即对各条沟泥石流的形成机理、运动和致灾方式等搜集了大量第一手资料,并结合室内分析整理,提出防治措施。认为在实施中应以防为主,防治结合,根据泥石流形成条件、运动规律,致灾方式等因地制宜,因害设防,并结合水土流失治理,改变生态环境,控制泥石流发展。防治中应以工程防治为主,进而达到综合治理,工程措施应在泥石流沟的形成区采取拦档措施,堆积区采用排泄措施,即上栏下排的工程治理,这样才能做到防患于未然。

The mountain located in Qinling Mountains of Shaanxi Province in Foping County is chosen as the research object on the debris flow disaster and its prevention and control situation. The methods of the prevention and control of geological disasters,through field investigation,to study the debris flow formation mechanism,motion and induced disasters were used a large amount of first-hand information is collected,combined with indoor analysis of consolidation,prevention measures and are put forward. Prevention and control measures in the implementation should be given priority to prevention,combining prevention with control,according to the debris flow formation conditions,regular exercise,disaster mode suiting measures to local conditions,fortification,and according to the soil erosion control,change the ecological environment,control the development of debris flow. The specific prevention measures should be based on the prevention of debris flow,and then reach comprehensive management,engineering measures should be formed in the region taking Blocking-Barring measures of debris flow accumulation area,the excretion is stopped. With these,we can nip in the mud.
