Abstract

The invention discloses an automatic deformation monitoring and early warning method that can be used in high fill and soft foundation engineering, which can realize the monitoring of the settlement deformation process of the monitored soft soil layer, and can realize the monitoring of the side slope of the monitored fill The monitoring of the displacement and deformation process has the advantage of high measurement accuracy, and the implementation of the present invention has little interference with the filling construction, which can ensure the accuracy of deformation monitoring and the stability of the construction process, and the monitored settlement deformation data can be used for high filling soil / soft foundation Provide a reliable basis for the prediction and effect evaluation of the post-construction settlement of the processing project, and the monitored deformation data of the adjacent slope can provide a reliable basis for the stability analysis of the adjacent slope and the layer thickness control during the filling process; Therefore, the present invention is especially suitable for the subgrade of high filling soil, soft foundation, land reclamation, embankment filling, large-area filling of port and wharf or vacuum preloading of soft foundation, etc. during construction or post-construction settlement deformation monitoring and edge monitoring. Displacement monitoring of high fill slopes.

Description

technical field [0001] The invention relates to a geotechnical engineering monitoring method, in particular to an automatic deformation monitoring and early warning method that can be used in high filling soil and soft foundation engineering. Background technique [0002] In hilly and mountainous areas, when constructing highways, ordinary roads, municipal engineering, construction, railways, water conservancy, port terminals, or electric power, it is inevitable to fill with soil, forming a large amount of high fill, and the maximum fill height is often dozens of Meters, or even hundreds of meters, need to be mechanically compacted, and the fill will have a certain degree of settlement during or after construction, and when the adjacent side slope is too high, the adjacent side slope is prone to slip and become unstable. [0003] In areas such as coastal areas, delta alluvial plains, river and lake sedimentary areas, or mountain valleys, large areas of silt, muddy soil or so...
