Experimental Study on Infiltration Time Effects of Mechanical Behaviors of Cement Soil

Abstract

Based on the safety and durability in the cement soil engineering about the pits anti-seepage and embankment impermeable walls, the experiments on the mechanical properties about the cement soil after infiltrated for some time have been carried out and the influential laws of infiltration time on the cement soil shearing strength, compressive strength and permeability coefficient have been obtained. The test results show that the infiltration time may have influences on mechanical behaviors of cement soil at different levels, and the infiltration time effects on mechanical behaviors of cement soil in the engineering applications and the designs such as impermeable walls should be taken into account; and the shearing strength and compressive strength of cement soil will decrease with the increase of infiltration time so that the curve regression equation about the shearing strength and compressive strength varying with the infiltration time has been established. And the permeability coefficient of cement soil will increase with the increase of infiltration time so that the curve regression equation about the permeability coefficient of cement soil varying with infiltration time has been established, too. The study result is significant and valuable to the safety and the durability of cement soil anti-seepage engineering.
