Abstract
The environmental geotechnical problems seriously affect the safety of geotechnical structure and the sustainable development of ecology. The pollution of laterite which is widely used in the infrastructure construction in Yunnan has been a grave threat to the safety of the laterite structure and groundwater as a result of the environmental problems. According to the proposed test plan for typical laterite and six ferric sulfate hydrate, different compaction work was prepared under different temperature, different moisture content and pollution for compaction sample of laterite, the concentration change of iron ion was analyzed over time, and characteristics of iron ions about the laterite migration change has been clear. The results of migrating, from the features of migrating change about iron ions, presents: at the same moment, with smaller compaction, higher moisture content, and the higher temperature, the migrating of iron ion in laterite is much faster, the concentration of iron ions is higher in the solution; at different moment, with time prolonged, it increases gradually, and it gradually reduces in the laterite. The research results will offer a theoretical foundation to the prevention and remedy of the laterite pollution in Yunnan, and will be very important in solving the problem of pollution caused by the discharge of pollutants. The results will also provide theoretical guide and technological support for the sustainable development of Yunnan economy and ecology as well as for the future laboratory experiments.
