The influence of step-by-step loading voltage start-up time on the soft clay reinforcement by electric silicification method
The step-by-step loading voltage method can effectively improve the post-treatment effect of electroosmotic treatment and reduce energy consumption.In this experiment,the electric silicification method was optimized by step-by-step loading voltage to solve the problems of low drainage rate,large energy consumption and serious elec-trode corrosion in the later stage of the test.Four groups of different step-by-step loading voltage start-up time tests were set up to study the best step-by-step loading voltage start-up time.The current and displacement during the ex-periment were monitored.The settlement,water content,shear strength of the soil after the test were analyzed.The energy consumption coefficient during each experiment was calculated,and the influence of different loading voltage start-up time on the electroosmotic treatment effect was deeply explored.The results show that the step-by-step load-ing voltage can effectively improve the electroosmotic treatment effect,and there is an optimal loading voltage timing for the step-by-step loading voltage.When the current decreases to 60%of the peak current,the loading voltage can effectively improve the electroosmotic drainage,increase the overall shear strength of the soil,the soil uniformity is better,and the energy consumption coefficient in the later stage of the experiment is reduced.
