Bridged-cemented flaky soft rock soil material and preparation method thereof

The invention relates to a bridging-cementation flaky soft rock-soil material, cement in bridging and cementation flaky soft rock-soil has a cementation effect, fine clay has a bridging effect, needle-shaped crystal cementation is generated at contact points of flaky soft rock-soil particles, and the fine clay enables the cement to form net cementation in overhead macropores, so that the bonding effect is good, and the bonding effect is good. The combined action of the two reduces the number of overhead macropores of the compacted soil; the bridged and cemented flaky soft rock soil comprises cement, flaky soft rock soil and fine clay. According to the invention, the doped fine clay can play a role in grading and filling flaky soil particles in the initial stage of compaction, and can reduce the porosity in the initial stage of compaction. After the flaky soil is maintained for 28 days, macropores are filled with a certain amount of fine clay, the fine clay plays a bridging role in the macropores, and short ne
