Landfill resistivity irregular factor test and engineering safety warning method and system

Abstract

The invention discloses a landfill resistivity irregular factor test and engineering safety warning method and system. The method comprises the following steps that in the whole process of landfill stacking body construction, operation and maintenance period, a data acquiring probe acquires a horizontal resistance signal and a vertical resistance signal of a landfill body which is tested by a landfill; a data acquiring control module calculates a horizontal resistance value and a vertical resistance value of the landfill which is tested by the landfill according to an unbalanced bridge principal; an intelligent control terminal calculates a resistivity irregular factor according to the horizontal resistance value and the vertical resistance value of the tested landfill body, thereby monitoring the change situation of the internal structure of the landfill stacking body in the whole process of construction, operation and maintenance period, and further performing landfill engineering safety warning. The system provided by the invention can be used throughout the construction of the landfill work, and has the advantages of simple and fast operation, continuousness and non-destructiveness, reliable result, low cost, easiness in promotion and the like, and filling the blank of landfill work risk evaluation and engineering safety warning, and has strong promotion and application values.

Description

technical field [0001] The invention belongs to the technical field of engineering safety monitoring and early warning, and in particular relates to a method and a system for testing the irregular factor of resistivity of a landfill site. Background technique [0002] Garbage sanitary landfill has always played an important role as the final disposal method of garbage, and it is still the main way of garbage disposal in most countries, including China. Although environmental protection engineering measures such as anti-seepage, compaction, covering and collection have been adopted for sanitary landfill, its characteristics such as large landfill height difference and high gas production still pose a potential threat to the safe operation of the landfill. In foreign countries, such as Turkey and the Philippines, there have been tragedies in which large landslides of garbage dumps caused biogas explosions and buried entire villages. Domestically, in 2002, a landslide occurred...

AI Technical Summary

Problems solved by technology

[0007] The present invention provides a method for testing the irregularity factor of resistivity in landfill sites and an early warning system for engineering safety of landfill sites, aiming to overcome the following problems of the traditional monitoring technology of geotechnical testing and engineering safety monitoring at the site of landfill sites Several deficiencies: 1) The convenience, speed, and real-time performance are not enough. The monitoring results are not closely integrated with geological, environmental, and construction data, and are not organically combined with the microscopic mechanism of deformation of the garbage dump, which makes it difficult to reasonably explain the monitoring results sometimes, resulting in monitoring results. The application level is low, and the early warning ability of engineering risk safety assessment is low
