The test of the chemical composition and content of pore water in the process of soil sample compression is of great significance to the research of soil pollution, the migration of pollutants in the soil, and pollution control. In the past, the chemical composition of pore water in the process of soil sample compression And content determination and related test methods have not yet been reported to apply for administrative protection, but the current scientific research projects need to test the composition and content of pore water, so it is necessary to develop a new triaxial or consolidation test process.

The invention discloses a testing device and a method for pore water chemical analysis on saturated soil in a three-axis or solidification testing process, and belongs to the field of geo-technical testing development water chemical analysis. The testing device comprises a testing processing control unit, a mining controller, a static three-axis or solidification pressure chamber and a trace water quality analyzer, wherein the testing processing control unit is linked with the mining controller; the trace water quality analyzer is equipped with a main machine for the water quality analyzer; the trace water quality analyzer is linked with the main machine for the water quality analyzer; trace water tested by using the trace water quality analyzer is water released from a compressed test sample; cylinders are arranged all around inside the static three-axis or solidification pressure chamber; the test sample is arranged at the central position inside the static three-axis or solidification pressure chamber; the test sample is wrapped with a latex membrane. The testing device has a great significance for study on problems such as soil body pollution, migration of pollutants in a soil body, and pollution control, and is relatively good in practicability and operability.
Description
technical field [0001] The invention relates to the expanded field of water chemical analysis for soil engineering tests, in particular to a test device and method for chemical analysis of pore water in saturated soil during triaxial or consolidation tests. Background technique [0002] The triaxial test or consolidation test of soil samples belongs to the category of soil mechanics tests. It mainly tests the mechanical indicators of soil samples in terms of deformation strength and other aspects under the action of vertical stress, but the compression process of saturated soil samples under the action of vertical stress At the same time, there will be pore water released. Due to the limited amount of pore water released, its chemical analysis items are mostly ignored. The ion chromatograph or liquid phase water quality analyzer is mainly used for the detection of drinking water, natural mineral water, sea water, etc. , such as K + 、Na + , Ca 2+ , NH + , Rb + 、Cs + , F...
