A Fill Settlement Prediction Method Based on Centrifugal Model Test

Abstract

The invention discloses a fill settlement prediction method based on a centrifugal model test, which relates to the technical field of fill engineering and includes the following steps: step S1, setting a special model box for the fill engineering settlement test, and the interior of the model box is a separate model space; step S2, Make centrifuge model samples of key nodes of the project, and make centrifuge model samples for the study of the general regularity of multi-parameter influence; step S3, data transmission between the model box and the centrifuge, and complete personalized model tests and generic model tests; step S4 , plot spatially scatter clusters, fit, smooth, and generate 3D spatial surfaces. The invention saves time cost and economic cost, can pre-simulate the filling settlement of objective entity working conditions, and can be used for comparison and selection of various alternatives and optimization of design parameters; three items related to settlement can be established at the same time Parameter relationship, and form a space surface, avoiding the cumbersome operations of field tests or numerical calculations.

Description

technical field [0001] The invention relates to the technical field of filling engineering, in particular to a filling settlement prediction method based on a centrifugal model test. Background technique [0002] With the rapid development of my country's economy and the rapid advancement of urbanization, many areas have experienced a shortage of construction land. Under the premise of moderate development, filling projects such as "cutting mountains and filling ditches", "rectifying ditches and making land", and "preserving the plains of Gumao" have become one of the important decision-making and development directions for the development, utilization and reserve protection of my country's land resources. [0003] The settlement and deformation of the land filling project directly determine the start time and construction sequence of the subsequent construction projects. When the ground settlement is too large, it will often affect the operation safety of the entire filling...

Problems solved by technology

However, the monitoring method is to bury a large number of settlement monitoring components inside the filling body, and monitor the settlement data manually for a long time, which is time-consuming, laborious and expensive

[0006] For the above technical problems, no effective solution has been proposed
