Abstract

The invention discloses an indoor quick load solidify tester and a relative method, belonging to the test technical field of deformation character index of rock project and building foundation. The device is composed of an upright load device, a solidify container for containing sample soil, a liquid pressure sensor, a deformation sensor, a static resistance strain gage, and a PC computer. And the test method comprises that (1), sampling, vacuuming until saturation, (2), putting the sample soil into the solidifying container, sealing the bottom of the sample and connecting with the sensor, (3), arranging the solidifying container into the upright load device, and mounting the liquid pressure sensor and the deformation sensor at relative positions, processing hole water pressure and upright deformation test, (4), using the static resistance strain device and the PC computer to pick, transmit and record static signal. The invention can be used in the condition with short construction period, high test accuracy and lack fund.

Description

technical field [0001] The invention relates to an indoor geotechnical test system and method, belonging to the field of geotechnical engineering investigation. It is mainly used for testing the deformation characteristics of the foundation of various buildings and structures, especially when the test conditions are not available on site, the construction period is tight, and the test accuracy is high, the method can be used to quickly and accurately measure the deformation characteristics of the building foundation. The obtained foundation deformation characteristic index is used for the foundation and foundation design of the building. Background technique [0002] Geotechnical test is a necessary means to provide scientific basis for geotechnical engineering design and construction. The consolidation test is an indoor scale model test that simulates the corresponding deformation of the foundation soil after being subjected to additional stress. ...
