Description
Technical field
The utility model belongs to geological disaster risk and assessment technology field thereof, relate to a kind of residual damming dam body under heavy rain, to form rubble flow face calamity early warning system, particularly a kind of be used for checked-up lake flood discharge after residual damming dam body under heavy rain, form rubble flow face calamity early warning system.
Background technology
The a large amount of checked-up lake of on May 12nd, 2008 and earthquake-induced occurred below, the existence of checked-up lake causes safely serious threat just as a time bomb to the resident in downstream, so national relevant unit has carried out artificial flood discharge to a large amount of checked-up lakes, the threat of the downstream people is temporarily eliminated, but it is again a challenge that the damming dam body that the thing followed is the instability remained after checked-up lake flood discharge forms huge rubble flow for us under heavy rain effect.Under heavy rain, form rubble flow for damming dam body residual after checked-up lake flood discharge and face calamity early warning system so necessary formation is a kind of and reduce the life of downstream resident is had very important significance safely.
Rubble flow is a kind of global disaster, and rubble flow is because its forming process is complicated, outburst is unexpected, break with tremendous force, last of short duration, that destructive power becomes a by force mountain area economy construction large disaster.The rubble flow that after rubble flow checked-up lake flood discharge different from the past, residual damming dam body is formed under heavy rain effect, producing a large amount of solids sources instantaneously, can have great destructive power, seriously jeopardizing people's life and property under heavy rain effect.So how to accomplish that early warning is to reduce the harm of rubble flow as much as possible to this kind of debris flow, aobvious is very important, the utility model, for the principal element combining wireless Sensor Network technology of debris flow, has very important significance to debris flow early-warning to reach.
In mud-stone flow disaster, why rubble flow is rubble flow, and mainly it is the special mighty torrent containing a large amount of silt and stone, so its character determines it must abundant solids source, and residual damming dam body both sides are distributed with a large amount of gravelly soil after checked-up lake flood discharge, the gradient is steeper, self stability is poor, be easy to collapse under the flood effect that heavy rain and heavy rain thereof bring out, formation for rubble flow provides abundant thing source, and the sensing module that therefore emphasis will be used in this method for early warning is exactly liquid level sensor, obliquity sensor and rain sensor.Also to consider if by pressure transducer, how they guaranteed that this method for early warning can not lose efficacy after losing efficacy, by sensor network technology by wireless network autonomous for a large amount of multiple types sensor node (sensing, collection, process, transmitting-receiving, network are in one) composition, realize the dynamic cooperation perception to physical world.It in real time, dynamically can obtain the heat transfer agent of physical world, and relevant information and communication backbone network are merged, achieve the extension of existing computer network virtual world to real physical world, change the mode that Human and nature circle is mutual, construct complete information system truly.Just based on this, be necessary that providing one under heavy rain, to form rubble flow for damming dam body residual after checked-up lake flood discharge faces calamity early warning system.
