【摘要】 探讨了由于环境因素变化诱发的物理化学和生物化学变化对岩土工程性质的影响，着重研究了有机质和微生物引起的氧化还原作用对起胶结作用的游离氧化铁赋存状态转化的影响。强调指出，这种影响可能导致岩土工程的安全问题。更多还原

【Abstract】 In this paper, the effect of physico-chemical and biochemical reactions caused by the variation of environmental facters on geotechnical engineering properties have been explored. Under the influence of redox caused by organic substances and microbes, the conversion in form of free iron oxide with cementation action has been ivestigated emphatically. It is pointed out that the effect probably causes safe problem in geotechnical engineering.更多还原
