Abstract

The invention discloses a visualization testing device for simulating soil body displacement of underwater open caisson construction and a method. The device comprises a seepage force application system, a working condition simulation system, a data collection system and an excavation simulation device. By fusing a transparent material technology and a digital image processing technology, the device is applied to indoor simulation of underwater open caisson construction, and visualization observation of a soil body displacement field and a seepage field in underwater open caisson constructionis achieved.

Description

technical field [0001] The invention belongs to the technical field of engineering tests, and in particular relates to a visual test device and a test method for simulating the displacement of submerged caisson construction soil. Background technique [0002] The caisson is a kind of underground building or structure that uses manual or mechanical methods to remove the earth and rocks in the well, sinks the wellbore underground to the design elevation through its own weight and various sinking-assisting measures, and fixes it in the ground, then completes the construction of the concrete bottom seal. Construction method. [0003] Over the past few decades, the completion of a large number of long-span bridges in my country has promoted the research on caisson foundation and the progress of construction experience. At present, caisson foundation, as an important form of deep foundation, has been widely and successfully used in a large number of ports, bridges, mines, water c...
