The research purpose is the change for acid pollution lateritic shearing strength indices and compressor characteristics indicial under different concentration of hydrochloric acid, differ curing time in text. The test result proven, acid pollution lateritic shearing strength indices and compressor characteristics indices population take on depress tide in company with hydrochloric acid concentration and curing horary Increase. Soil intensive parameter toward structure stability and safeness calculation take on important significance, yet soil mechanics parameter isn't unchangeable in structure specifical load zone of influence, it suffer external environment's influence somewhat change, at times even change very large, those with raw soil sinew learn parameter for gist designed structure likelihood move towards be faced with unstability or surfeit sedimentary danger. Environmental condition variance in to soil mass behaviour's influence also more and more of came in for occupation natural attention, Fang xiao yang[1] thought nowaday geotechnical engineering theory and method primarily gist mechanical energy determinate, mechanical energy to geotechnical engineering behaviour play a central role, yet in the process of time, earthy property no longer except by mechanical energy ground control, environmental energy ground factor like wetting and drying cycle grade would change soil grain property, thereby change earthy engineering properties, just this kind of influence affect take on a long term. The laterite resource that is widely distributed in Yunnan, seriously threaten to the safety of laterite structure and ecological environment and sustainable development Because by the various forms of pollution. In engineering, contaminated by acid clay, soil strength significantly reduced, leading to instability or destruction of superstructures, triggering a series of engineering accidents. Therefore, research is contaminated with acid laterite contamination mechanism to stabilize the construction quality traits, protecting the environment is important, but also for taking reasonable and proper remediation measures provide theoretical support.
