    PRELIMINARY STUDY ON TERTIARY ENGINEERING GEOLOGICAL CONDITIONS IN BEIJING PLAIN AREA

    • 摘要: 随着北京市地下空间开发的深层化发展,关于北京市第三纪工程地质条件的研究的重要性逐渐凸显。相对于第四纪工程地质,这方面的研究相对薄弱。本文在系统分析大量工程地质资料的基础上,根据沉积学一般原理,首次从地质构造角度对北京平原区第三纪沉积规律进行了系统研究,获得了一系列重要结论,并此基础上进一步结合大量的钻孔地层资料和物理力学试验资料对中心地区(336km2面积,100m深度范围),进行了工程地质统一分层的探讨,为今后中心地区深部地下空间规划提供了重要技术支撑,同时也为进一步的第三纪地质条件、尤其是工程地质条件研究提供了可借鉴的方法与思路。

       

      Abstract: The development of underground space has gone towards deep earth in Beijing City. The importance of the study on Tertiary engineering geology is increasing prominently. The Tertiary engineering geology is weak in contrast to the Quaternary engineering geology in Beijing.Based on the analysis of abundant engineering geological data and according to the general theory of sediment, the Tertiary sediment is discussed systematically from the point of geological structure for the first time. A series of conclusions are deduced. On the basis of the data of borehole and physical mechanical test, the unified engineering geological stratum is further discussed. It is an important support for the planning of the deep underground space in the Center region (with the depth of 100m and area of 336km2) of Beijing City. At the same time, it serves good references for further study on the Tertiary geology, especially Tertiary engineering geology from methodology and idea.
