A monitoring system and control evaluation method for soil foundation strength of airport runways in permafrost regions

Abstract

The present invention is a frozen soil zone airport runway soil matrix strength monitoring system and a control evaluation method, the frozen soil zone airport runway soil matrix strength monitoring system includes a plurality of buried type data acquisition modules, a data collection module and a monitoring evaluation module, theburied type data acquisition module comprises a temperature sensor, a displacement sensor, an industrial computer, a memory, a Bluetooth transmitter and a solar storage battery, the data collection module is a tablet personal computer with Bluetooth connectivity function, and the monitoring evaluation module is a computer with monitor evaluation software. According to the frozen soil zone airport runway temperature rise effect monitoring evaluation system and the control method, soil matrix deformation in aircraft take-off and landing and taxiing processes can be dynamically tested and recorded, influence of the temperature rise effect on a frozen soil zone airport runway can be detected and evaluated, a method to enhance the safe operation support capabilities of airports in cold zones is provided, and the method is scientific and rational, convenient in construct, and easy to promote and use.

Description

technical field [0001] The invention belongs to the technical field of airport engineering, and in particular relates to a soil foundation strength monitoring system and a control evaluation method of an airport runway in a permafrost region. Background technique [0002] With the continuous development of the civil aviation industry, more and more airports are put into operation. With the increase of operating time, many practical engineering problems have been exposed, especially for airports built in permafrost areas. During the freezing and thawing of groundwater in spring and autumn, it is very easy to cause frost heave and cause pavement damage. Mohe Airport is the first civil airport built in the permafrost area in my country. With the continuous increase of airport construction in special environments, the Civil Aviation Administration of China has proposed the research direction of civil aviation airport construction in "special environments". [0003] However, in ...

AI Technical Summary

Problems solved by technology

[0003] However, in actual engineering, we can only learn from the practical experience in related transportation fields such as railways and highways. There is still a lack of sufficient research on the wide-width road structure with a relatively short airport runway and a significantly increased width.

In particular, there is a lack of sufficient monitoring data for engineering damage caused by the above-mentioned temperature rise effect
