Abstract

The invention discloses a soil layer sedimentation tester and a test method thereof. The tester comprises three parts namely an experiment device, a pressure loading device and a measurement device, wherein a transparent inner cylinder and an outer cylinder are arranged on a base; a water inlet is formed in the upper part of the outer cylinder; a water outlet is formed in the lower part of the outer cylinder; water leak holes are formed in the wall of the inner cylinder; a top plate is arranged at the upper part of the inner cylinder; a jack is arranged at the upper part of a reaction frame; a dial gauge is mounted at the end part of a dial gauge bracket; the three parts are combined closely and work together. The invention discloses the soil layer sedimentation tester for measuring soil layer sedimentation under the influence of underground water periodic variation and the test method of the tester; the weight stress on the soil layer is simulated through controlling the external load on the soil layer and the periodic variation of underground water level is simulated through controlling the variation of water level between the inner cylinder and the outer cylinder, so that the soil layer sedimentation rule formed under the influence of underground water periodic variation is obtained.

Description

technical field [0001] The invention relates to a soil subsidence tester capable of measuring the settlement and rebound of the soil layer under the action of the groundwater cycle, in particular to a soil subsidence tester used for surface subsidence analysis in the fields of roads, railways and buildings . The invention also relates to a test method of the soil layer settlement tester. Background technique [0002] The subsidence of soil layer under the periodic circulation of groundwater refers to a phenomenon that the soil layer consolidates under the action of external load, periodic circulation of groundwater and various other external forces. [0003] At present, surface subsidence has become a problem that cannot be ignored in the fields of road, railway and housing construction, and various accidents caused by uneven subsidence of the ground surface occur from time to time. Especially in areas where groundwater is active and changes periodically, land subsidence i...
