High-backfill deformation wireless remote integrated monitoring system and mounting and monitoring method

Abstract

The invention relates to a high-backfill deformation wireless remote integrated monitoring system and a mounting and monitoring method. The system is composed of a sensor system (1), a data collecting system (9), a wireless transmission system (13) and a data management and analysis system (17). The mounting and monitoring method comprises the steps that 1, the sensor system is embedded and mounted, wherein a, a single-point settlement sensor is embedded and mounted, b, an earth pressure cell is embedded and mounted, c, a pore water pressure gauge is embedded and mounted, d, a soil humidity sensor is embedded and mounted, and e, a clinometers is embedded and mounted; 2, the data collecting system is designed and mounted; 3, the wireless transmission system is mounted and debugged; 4, the data management and analysis system is mounted; and 5, implementation of the monitoring system is carried out. Wireless remote integrated monitoring can be carried out on deformation and stability of high-backfill foundations and high-backfill slopes in the backfill construction process or after construction, early warning is carried out on geological disasters possibly caused by deformation of the high-backfill slopes, changes of groundwater environment and the like, and informatization design and construction are achieved.

Description

technical field [0001] The invention relates to the field of high filling deformation monitoring, in particular to a wireless remote comprehensive monitoring system for high filling deformation and an installation monitoring method. Background technique [0002] Under the untouchable red line of "1.8 billion mu of arable land", most of the construction land needed for the urbanization of mountainous areas and the implementation of the "Belt and Road" strategy is solved by cutting mountains and filling ditches to create land. Generate a large number of high-fill foundations and high-fill slopes. For example, Luliang Airport in Shanxi has a maximum fill of 81.9m, and Jiuhuang Airport in Sichuan has a high fill airport project with a maximum fill height of 102m; in addition, Shiyan, Lanzhou and Yan'an are all undergoing large-scale flat mountain land reclamation projects. Lanzhou New District started in 2012 Level the land about 25km 2 , Yan'an Phase I Project (North District...

Problems solved by technology

Because the design method is immature, during the construction of high fill, engineers often use the so-called information construction technology, that is, to monitor the construction process through manual frequent deformation observation (see Table 1 for the current routine monitoring items and monitoring methods of high fill). And feedback the observation results in time for decision makers to adjust the design and construction reference, but this can only rely on the experience and judgment of engineers, and the above-mentioned information construction technology is mostly blind and passive

For example, in Table 1, the monitoring methods for surface deformation monitoring and internal deformation horizontal displacement of high fill are too traditional,
