Test study on solidification process of silt mud for levee construction in Nansha area of Guangzhou city

In order to solve the contradiction of silt-mud storage difficulty in river harnessing and insufficient soil sources in road construction,the test of silt-mud solidification for levee construction was carried out in the Wuzhou river levee construction.In the test,the new silt-mud solidification technology was introduced.This technology is to mix solidification material in silt-mud to change its physical featues and increase silt-mud strength in a short time.In the Wuzhou river harnessing,a 30 m levee was selected as test section,through prototype parameters check such as dry density,unconfined compression strength,shear strength,bearing pressure of foundation,sedimentation,seepage etc.,some valuable achievements were obtained,which can be referred in this technology application and dissemination.
