Description

A kind of intelligent geological calamity synthetic monitoring system and multi-stage prediction analysis method
Technical field
The invention belongs to technical field of physical automatic control, particularly a kind of intelligent geological calamity synthetic monitoring system and multi-stage prediction analysis method.
Background technology
The geologic hazard monitoring is that collection geologic hazard formation mechanism, monitoring instrument, space-time technology and prediction technology are the complex art of one.The monitoring technology method research of current domestic and international geologic hazard mostly is to center on that sudden geology disasters such as avalanche, landslide, rubble flow carry out with using.
Monitoring method is mainly to be divided into four big classes at the parameter type that detects.It at first is the monitoring of disaster body deformability, comprise monitoring method: as the underground deep deformation of disaster body, surface deformable and relative displacement monitoring, face of land absolute displacement monitoring based on the Displacement Measurement deformation data, such technology is comparatively ripe at present, precision is higher, and the Chang Zuowei routine techniques is used for the geologic hazard monitoring; Because what obtain is directly perceived, direct information, particularly displacement deformation amount, often becomes one of main foundation of prediction.
Next is a change information such as monitoring disaster body physics, chemical fields, measures as stress monitoring, earthquake sounds monitoring, radioelement (radon gas, mercury vapour) measurement, geochemical method and earth pulsation.Be used for the variation of the contained radioactive element of disaster body (uranium, radium) decay product (as radon gas) concentration, chemical element and physical fields thereof such as monitoring landslide at present in the world, physics, the chemical fields of geologic hazard body change, often with the deformation failure close relation of disaster body, with respect to displacement deformation, have advanced.
Monitor the geologic hazard groundwater activities in addition, be rich in feature, water quality characteristic is main monitoring method.As underground water table (or groundwater pressure) monitoring, monitoring pore water pressure and quality of groundwater monitoring etc.The formation of most of geologic hazard, development groundwater activities all inner with the disaster body or on every side is in close relations, and in the process that the disaster body generates, phreatic feature own is also corresponding to change simultaneously.
Be the risk factor monitoring at last, mainly comprise monitoring technology method: weather monitoring, groundwater dynamic monitoring, seismic monitoring, human engineering movement monitoring etc. based on monitoring geologic hazard risk factor.Rainfall, groundwater activities are the main predisposing factors of geologic hazard; Rainfall amount size, spatial-temporal distribution characteristic are one of main discriminant criterions of evaluation region geologic hazard (particularly collapsing, slide, flow the differentiation of three big geologic hazards); The human engineering activity is one of main predisposing factors of modern geologic hazard, so the monitoring of geologic hazard risk factor is the important component part of disaster monitoring technology.
Domestic having many individual events or two measuring instruments aspect the geologic hazard monitoring, they are subjected to some limitations in the application aspect the prediction.
The main reason that geological calamity synthetic monitoring device monitoring geologic hazard forms, it is the synthesis that each monitoring modular constitutes, or the causal analytic intelligent organic system of geologic hazard.The monitoring content comprises deformation displacement, physics and chemical fields, risk factor, groundwater activities etc.Wherein deformation displacement adopts non-contact detection, when guaranteeing precision, emphasize intuitive, simplicity and low cost, introduce new and high technology the disaster body carried out the stereoscopic monitoring of multi-angle, be refine, optimize, the integrated project of progressive, brand-new research and development, prediction.
The kind of existing geologic hazard monitoring instrument and monitoring content
The kind of the geologic hazard monitoring instrument of this problem research and development and monitoring content
Native system is not the simple combination of above-mentioned various single monitoring devices, but the lifting on monitoring principle and technical method and integrated.Because disaster is the result of a series of inside and outside complicated factor combined actions, thereby need could carry out accurate forecast to disaster to multiparameter analysis, thereby loss is dropped to minimum.
The geologic hazard origin cause of formation is the system ensemble of amount complicated and changeable, wherein certain single parameter is in critical conditions and might not represents that disaster be about to take place, facts have proved and to forecast comparatively correctly that geologic hazard needs multiparameter to monitor simultaneously, and also need to know under the normality each parameter and face of land evolutionary process mechanism of action that is mutually related, and a certain parameter reaches and can quicken the chain reaction that occurs after the critical value.These relations are the results that study for a long period of time, sum up.Thereby the supervisory system of research and development geologic hazard, satisfy large tracts of land, long-term, real-time, unattended monitoring requirement, no matter to reducing the harm of extreme event (shake, heavy showers doughtily) the secondary geologic hazard of deriving, the mechanism of causing disaster that still discloses geologic hazard all has crucial meaning.
