摘　　要：自周口店北京人遗址区被发现后的几十年以来,由于自然和人为因素的影响,在各发掘点内出现了诸多不同类型的地质病害,严重威胁着遗址区的安全与保护．基于此,通过现场及室内试验对遗址区环境工程地质条件进行了分析并在此基础上通过岩石薄片镜下鉴定、岩石化学分析及崩解试验等对影响遗址区病害的因素及机理做了分析．结果发现,用口店遗址区7个发掘点共有20处类型不一、规模不等、变形程度不同的潜在地质病害点．其破坏的原因可以归结为地质、环境及人类活动3个因素,其中着重讨论了环境因素的影响．环境因素分析结果表明,不同地点处由于其胶结物成份不同所以环境因素对其的影响方式也不同．图12,表3,参8．Peking Man Site in Zhoukoudian is well-known palaeoanthropie culture site in the world. For tens of years since its discovery, due to natural and factitious factors there were appeared many different types of geological diseases which have threatened safety and protection of the Peking Man Site .Therefore, environment geological conditions of Peking Man Site were analyzed by field investigation and lab test, and on the basis of that causes and mechanisms of diseases of the Site were analyzed by means of microscopic identification of rock slice, mechanical analysis, disintegrity test and so on. The results indicate there are twenty potential geological diseases at seven excavation places. The reasons of geological diseases are summed up to three factors： geology, environment and human activity. The result of environment analysis makes clear that different types of cementation decide on different weathering modes of rock or breccia. 12figs., 3tabs., 8refs.
