Examples
Example Embodiment
[0041] Example 1
[0042] Take the silty soil sample numbered 1, remove the soil sample impurities before the test, weigh 600g soil sample, and bring it into the formula (1) according to the converted code value in Table 3. The formula (1) is simplified to Y= 1290.77+124.72X 3 +9.92X 3 2 ; Add different amounts of curing agent according to the ratio (weight percentage of each component: cement 46%, slag 34%, fly ash 15%, triethanolamine 5%), when the content of the curing agent changes from 6% to 12% , Stir the mixture to make 3 Parallel specimens of cylinders, standard curing for 28 days. The strength value of solidified soil is shown in Table 4:

Example Embodiment
[0046] Example 2
[0047] Take the muddy soil sample No. 2, remove the impurities of the soil sample before the test, weigh 600g of the soil sample, and put it into the formula (1) according to the converted code value in Table 3. The formula (1) is simplified to Y= 1270.48+122.26X 3 +9.92X 3 2 ; Add different amounts of curing agent according to the ratio (weight percentage of each component: cement 46%, slag 34%, fly ash 15%, triethanolamine 5%), when the content of the curing agent changes from 6% to 12% , Stir the mixture to make 3 Parallel specimens of cylinders, standard curing for 28 days. The strength value of solidified soil is shown in Table 5:

Example Embodiment
[0050] Example 3
[0051] Take the silt soil sample numbered 3, remove the soil sample impurities before the test, weigh 600g soil sample, and bring it into the formula (1) according to the converted code value in Table 3. The formula (1) is simplified to Y= 1236.57+118.96X 3 +9.92X 3 2 ; Add different amounts of curing agent according to the ratio (weight percentage of each component: cement 46%, slag 34%, fly ash 15%, triethanolamine 5%), when the content of the curing agent changes from 6% to 12% , Stir the mixture to make 3 Parallel specimens of cylinders, standard curing for 28 days. The strength value of solidified soil is shown in Table 6:
