Fill valley foundation settlement inversion method based on centrifugal model test

Abstract

The invention discloses a fill valley foundation settlement inversion method based on a centrifugal model test. The method comprises the steps of 1, obtaining solid fill engineering profile parameters; 2, manufacturing a model box, and carrying out a centrifugal model test on the model box to obtain model filling settlement data; 3, manufacturing a rigid valley foundation model box, and carrying out a centrifugal model test on the rigid valley foundation model box to obtain model filling settlement data; 4, manufacturing a flexible valley foundation model box, and carrying out a centrifugal model test on the flexible valley foundation model box to obtain model filling settlement data; and 5, carrying out settlement inversion on the original valley foundation of the fill project. Accordingto the method, the long-term deformation of the original valley and the later-period filling soil can be visually displayed in a short time, the model boundary condition is clear, the inversion idea is concise, the additional settlement interval value of the original valley foundation of the fill engineering under the action of the overlying filling soil load can be rapidly obtained, and the method can be used as an auxiliary means for fill engineering design and engineering settlement prediction.

Description

technical field [0001] The invention belongs to the technical field of subsidence measurement of original valley foundations of filling engineering, and in particular relates to a settlement inversion method of foundations of filling valleys 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 filling and land reclamation project directly determine the start time and construction sequence of the follow-up construction project...

AI Technical Summary

Problems solved by technology

[0004] In the process of existing engineering practice, builders often only pay attention to the settlement of the newly filled body and ignore the settlement of the original valley foundation. Moreover, the traditional on-site monitoring method is not only time-consuming and laborious, but also expensive and significantly disturbed by construction. It is separated and peeled off from the settlement of the original valley foundation, which is not conducive to the analysis of specific settlement causes
