[0048] As an embodiment of the present invention, the process diagram of the first method for treating collapsible loess foundation includes the following steps. First, as figure 1 As shown in a, the dynamic ramming method is used to ram the surface soil of the foundation with rammer 1, and then, as figure 1 As shown in b, the hole is formed to a certain depth to form the perfusion hole 2, and then, as figure 1 As shown in c, fill the filler 3 at the bottom end of the pouring hole 2 through the pouring hole 2, and tamping with a slender hammer 4, and then, as figure 1 As shown in d, pour water 5 into the pouring hole 2 and fill it with sand and gravel 6 until a certain distance from the surface of the foundation. Finally, as figure 1 As shown in e, the soil of the foundation gradually produces self-weight collapsibility after being immersed in water, until the collapse and deformation are stable.
