Abstract1994-04-30的11:45,四川省武隆县兴顺乡核桃坪村境内乌江左岸鸡冠岭一龙冠嘴(107°29′27″E,29°28′06″N)发生了特大型滑坡→崩塌→碎屑流→堵江灾害链,其碎屑堆积物方量530万m ̄3.崩塌滑坡发生区海拔500─850m。崩塌滑坡物质解体、破碎后,又呈碎屑流作顺坡运动,其中30万m ̄3泻入乌江(江面海拔150m),堵断江流时间达30min;这次灾害链致死4人,失踪12人,伤5人,造成直接经济损失近千万元。发生区后缘坡体上还有地表裂缝在不断扩展,潜在性灾害威胁继续存在。
Other AbstractAt 11:45 On April 30,1994, a hazard-chain of lands1ide → collapse→debris flow→riverstoppage occurred at Jiguanling─Longguanzhui(107°29′ 27″E,29°28′06″N),located on the leftbank of Wujiang River in Wulong Couuty , Sichuan Provin ce, The volume of debris flow wasabout 5.3M(m) ̄3。The altitude of the occurring area is at 500─800m。 After resolving,the debris moved alongthe slope。0. 3M(m) ̄3 of them put into Wujiang River and 0.1M(m) ̄3 of them piled below theriver level,The time of river stoppage lasted 30min。This hazard-chain caused 4 persons dead,12 ones lost and 13 wounded, The economic lossesare nearly 10 M yuan(RMB)。There are cracks which have been developing on the beck of the occurrmg area,The potentialhazard still exists。Some countermeasures against hazard as follaws:1. clearing off unstabe rock mass;2.a longmeasuring and predicting for the cracks on the ground;3. setting up catch structure along the roadbesltie the river and rationaly plan ning waste residue of coal so that prevent sliding mass turninginto debris-flow;4.the effect of explod to unstable rock should be lessen
