Experimental Study on the Mechanism of Steel Slag Concrete Pile-soil Interaction
By designing a pile-soil interaction visualization test device,the simulation of steel slag concrete pile to reinforce the dredger fill foundation was carried out.The water content,pore pressure value of the soil around the pile and the disturbance of the pile to the soil were monitored and analyzed.The physical and chemical reactions and their products between the pile and the soil were studied in depth by using the combination of macro,meso and micro test methods.The test results show that the pile has the effect of expanding and compacting the soil.The pile body can accelerate the drainage and decompression process of the soil;the physical and chemical reactions between piles and soil and their products have a positive strengthening effect on the stability of the foundation.
