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, and there are many measurement interference factors, large errors, time-consuming and labor-intensive, and cannot achieve real-time monitoring; the construction of instruments for layered settlement monitoring of internal deformation is inconvenient 1. The position where the settlement pipe is buried is inconvenient for compaction work, and the construction of dynamic compaction or impact rolling is easy to damage; groundwater monitoring generally only monitors the water level, and the water content, pore water pressure and earth pressure during and after the construction of high fill do not change. See examples of integrated monitoring

Therefore, the design and construction experience of high fill deformation is insufficient, and accidents occur frequently
