Fill settlement prediction method based on centrifugal model test

Abstract

The invention discloses a fill settlement prediction method based on a centrifugal model test, and relates to the technical field of fill engineering, and the method comprises the following steps: S1,setting a special model box for a fill engineering settlement test, and enabling the interior of the model box to be a separation model space; S2, manufacturing a centrifugal model sample of the engineering key node, and manufacturing a centrifugal model sample of general regularity research of the multi-parameter influence; S3, performing data transmission with a centrifugal machine in the modelbox, and completing a personalized model test and a generic model test; and S4, drawing a space scatter cluster, performing fitting, performing smoothing and generating a three-dimensional space curved surface. According to the method, time cost and economic cost are saved, fill settlement of objective entity working conditions can be simulated in advance, and the method can be used for comparison and selection of multiple alternative schemes and optimization of design parameters; three parameter relations related to settlement can be established at the same time, a space curved surface is formed, and tedious operation of field tests or numerical calculation is avoided.

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 creating land", and "protecting plains in 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 p...

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
