| description | Methods of ground treatment of the sea dike foundation in Wenzhou Peninsula Construction Project are discussed. It is concluded that soil stabilization is a good method for its low cost and short construction period. Unconfined compression tests were carried out at different levels of water content, air temperature and age to determine the optimal stabilizer mixing ratio and the properties of strength gain of the stabilized soil. Results are summarized as follows: at the mixing ratio of 6%, the stabilized soil can be used as subbase filling, and at the mixing ratio of 10%-12%, the strength of the stabilized soil attained the bearing capacity of foundation soil. The strength of the stabilized soil decreased by 15%-40% at a temperature drop of 10 ℃, and the higher the stabilizer mixing ratio was, the less remarkable of the temperature effect would be. A 5.8% decreases in the water content increased the strength of the stabilized soil by 8%. The stabilized soil cured in air was found to have a stabilization strength 1.5 times of the soil cured in sea water. Based on laboratory tests, two construction ways of the soil stabilization were suggested: one is mixing the silt with stabilizer first, followed by casting the stabilizer soil into the subbase of sea dike under sea water; the other one is dredging the silty soil into a close area, followed by reinforcing the subbase and the foundation soil as a whole by deep mixing. |
