Embodiment 2
[0039] Example 2, the test mold is composed of a cylinder and a compacting block, wherein the inner diameter of the cylinder is 61.8mm, and the height is 205mm, and there are six compacting blocks, all of which are 61.8mm in diameter, of which there are four The height is 25mm (the same as the height of each layer of the formed sample), and the other two are 40mm, one of which is used as the bottom plate. The total height of the six compacted blocks plus the height of the single-layer soil sample is just equal to the height of the cylinder . The specific operation method of sample preparation is as follows:
[0040] 1. Select the test soil sample, air-dry, crush, and sieve (pass through a 5mm sieve), measure the air-dried moisture content, and calculate the required water amount according to the optimal moisture content of the soil sample.
[0041]2. Spray the amount of water to be added on the soil and mix well, put it in a plastic bag after standing still for a while, and t...
