Abstract

The invention relates to a method for testing the moisture content of saturated soil samples, which mainly includes the following steps: firstly, taking a soil sample, then encapsulating the soil sample in a conductive sample chamber, then connecting the conductive sample chamber into a circuit, and passing the ammeter and The voltmeter detects the current flowing through the conductive sample chamber and the voltage across it, and then calculates the resistance value, volume and mass of pore water in the soil sample, and finally calculates the moisture content of the saturated soil sample. This method is based on the electrical principle that water in saturated soil is connected, and current will flow when both ends are energized. Combining the conductivity of water with the volume and mass of water, the water content of saturated soil can be measured quickly and conveniently, and the operation is simple. The traditional tedious operations such as multiple weighing and drying are avoided, and the operability is strong, which can greatly reduce the cost.

Description

technical field

[0001] The invention relates to the technical field of geotechnical experiments, in particular to a method for testing the moisture content of saturated soil samples. Background technique

[0002] In the process of geotechnical engineering experiments, it is extremely important to measure the saturated water content of soil samples, which is the basis of subsequent experiments. Saturated soil refers to the soil filled with water in the pores. This kind of soil has a high water content, and the traditional drying method is time-consuming, and the internal moisture is not easy to dry. The difference between saturated soil and unsaturated soil is in the moisture content. The index of moisture content reflects the dryness and wetness of the soil sample. Usually, the weight of water and the weight of dry soil should be measured.

[0003] Moisture content is an important index of soil samples, which directly affects the shear strength and compaction degree of soil...
