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.
Since the discovery of the Beijinger site in Zhoukoudian several decades ago, due to natural and man-made factors, many different types of geological disasters have emerged in various excavation sites, seriously threatening the security and protection of the site. Based on this, the environmental engineering geological conditions in the site area were analyzed through on-site and in-house experiments and the factors and mechanisms affecting the site disease were analyzed based on the identification of rock thin slices, petrochemical analysis and disintegration test . The results showed that there are 20 potential geological disasters with different types, sizes and degrees of deformation in the 7 excavation sites of the site of Umukou site. The reasons for its destruction can be attributed to the geological, environmental and human activities, three factors, which focused on the impact of environmental factors. The results of environmental factors analysis show that environmental factors have different influence on the different locations because of the different components of cement.
