| 摘 要： | 通过对广州市区一般工程建设影响深度范围内的岩土条件分析,将区内的工程岩土划分出12个主层,46个亚层,并指出了各亚层的状态范围与次亚层划分。在工程岩土分层的基础上通过区域工程地质大剖面的带状岩土条件解剖,应用历年市政工程勘察资料结合其他地质研究成果,进行工程岩土环境分区,划分出4个I级工程岩土环境区,11个II级工程岩土环境区。通过各工程岩土环境区的岩土特征研究,做出了各区的工程建设适宜性评价。本文属广州地区首次进行的工程岩土统一划层、区域工程岩土大剖面剖析及系统工程岩土环境分区的综合研究,是数字城市建设必须先行解决的基础问题,就尚在进行建设的众多工程地质数字系统建设应予以充分重视,确保系统建成后的有效性。

| Abstract: | Thragh the analysis on the geotechnical data of the strata penetrated in the general engineering projects of Guangzhou city, foundation rock-soil may be divided into 12 main strata and 46 substrata, status and scope of all the substrata and division of hypo-substrata are introduced. Based on the division of strata, large regional ribbon geological profiles are anatomized, having incorporated past years the city engineering investigates data and other geological research results, engineering rock-soil environment is zoned into four Ⅰ grade zones and eleven Ⅱ zones. Through rock-soil mass characteristic study on each engineering geotechnical environment zone, evaluations on suitability of each zone's engineering construction above are drawn. The paper is the first time to synthetically research on wholly division of rock-soil mass strata, anatomization of large regional geological profiles and zoning of the engineering geotechnical environment Guangzhou vity. which needs to be solved before digital city commence to construct. Many digital engineering geology system in building should be fully paid attention so as to guarantee validity of the future finished system. |
