Embodiment

[0041] For saturated soil, the soil is generally gradually compressed, part of the water is discharged from the soil, and the excess static pore water pressure in the soil is correspondingly converted into effective stress until the deformation becomes stable. This process is called consolidation. The device of the invention is used for simulating layered saturated soil consolidation experiments to show students the mechanism of saturated soil consolidation and improve classroom teaching effect.

[0042]A device for simulating seepage and consolidation of stratified saturated soil according to the invention comprises a container device, a spring-piston device, a loading device, a water supply and drainage device and a measuring device. The container device includes a water container 1 and a collection container 2. The water container 1 and the collection container 2 are connected by a water supply and drainage device. The spring-piston device is arranged inside the water contai...

Abstract

The invention relates to a layered saturated soil seepage consolidation simulating device which comprises a container device, a spring-piston device, a loading device, a water supply and discharge device and a measuring device. The container device comprises a water container (1) and a collection container (2) which are connected through the water supply and discharge device, the spring-piston device is arranged inside the water container (1) and used for simulating a layered soil body, the loading device is fixed at the top of the spring-piston device and applies a load to the spring-piston device, the water supply and discharge device is arranged on the loading device, and the measuring device is arranged on the side wall of the water container and used for measuring static water pressure. Compared with the prior art, the layered saturated soil seepage consolidation simulating device has the advantages that the simulating device is simple and convenient in connection and can simulate soil frameworks and void ratios of the layered soil different in elasticity modulus, experiments are close to real environment, and the layered saturated soil seepage consolidation simulating device has good effect on helping in understanding a Terzaghi one-dimensional consolidation theory.

Description

technical field [0001] The invention relates to a soil seepage consolidation simulation device, in particular to a layered saturated soil seepage consolidation simulation device. Background technique [0002] Soil mechanics is an important technical basic course for civil engineering majors. The problem of seepage and consolidation of saturated soil is a very important research topic in soil mechanics. Because it involves a lot of mechanical physics concepts and the relevant knowledge is relatively abstract, traditional teaching methods usually Theoretical formulas are deduced using a large number of mathematical symbols on the blackboard. It involves the effective stress of the soil, the pore water pressure, and the change of soil settlement with time. is a challenge and difficulty. In order to enable students to better understand and master the knowledge of saturated soil seepage consolidation, the spring-piston model is often used as an auxiliary means in teaching to des...
