Abstract

Based on the safety and durability in the complex environment, the experiments on unconfined compression strength about the cemented soil after eroding in sodium sulfate solution have been carried out and the influential laws of different concentration of sodium sulfate solution and eroding time on the cemented soil unconfined compression strength have been obtained. The test results show that the different concentration of sodium sulfate solution and eroding time may have influences on erosion effect of unconfined compression strength of cemented soil at different levels. If the ionic concentration of sodium sulfate solution is small, the solution has little erosion effect on the unconfined compression strength of cemented soil. But the unconfined compression strength will decrease with the increase of eroding time, and the erosion effect of unconfined compression strength will increase with the increase of eroding time. The study result is significant and valuable to the safety and the durability of cemented soil engineering.
