Embodiment Construction

[0120] The computer data forecasting and processing system processes the aging data of the monitored object provided by the data acquisition and transmission system with the creep aging forecasting method, and outputs the processing results; the creep aging forecasting method is:

[0121] (1) According to the actual monitoring trajectory curve, according to the second derivative of the curve It is divided into three periods of germination rheology, steady state creep and unstable creep. During the period of germination rheology, the second derivative of the curve is positive; in the period of steady state creep, the second derivative of the curve is negative. d 2 y dt 2 0 ; Unstability creep period. The second derivative of the curve is positive, d 2 ...

Abstract

The invention belongs to an environmental disaster monitoring and forecasting system which comprises a data acquisition and transmission system and a computer data forecasting and processing system, wherein the data acquisition and transmission system is connected with the computer data forecasting and processing system and is used for providing the aging data of a monitored object for the computer data forecasting and processing system; and the computer data forecasting and processing system is used for processing the aging data of the monitored object provided by the data acquisition and transmission system by using a creeping aging forecasting method, and outputting the processed result. The invention can accurately predict and forecast the occurrence time, scale and developing trend of landslides and earthquakes with sufficient accuracy, thereby basically achieving the purposes of prevention and reduction of disasters.

Description

technical field [0001] The invention belongs to an ecological disaster monitoring and forecasting system. Background technique [0002] Earthquakes and landslides are among the top ten natural disasters in the world. my country is a mountainous country. According to statistics, landslide disasters have become the second largest geological disaster after earthquakes. With the continuous expansion of human activities, especially the scope and scale of human engineering activities, the frequency and possibility of landslides are increasing, and the harm to society is also increasing. [0003] Since the study of landslide hazards began in the middle of the 19th century, experts and scholars in the geotechnical field at home and abroad have attached great importance to the research on the dynamic law and prediction of landslide disasters. For example, both Switzerland and the United States have conducted decades-long observations on some key landslides. . The former Soviet Uni...
