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。
The influence of physical and biochemical changes induced by environmental factors on the geotechnical engineering properties was investigated. The effect of redox caused by organic matter and microorganisms on the transformation of free iron oxides that acted as cementation was investigated. It is emphasized that this effect may lead to safety issues in geotechnical engineering.
