太原市漪汾大厦岩土工程勘察实例

A survey example of rock-soil engineering of Yifen great building in Taiyuan

为了获取准确的第一手钻探记录资料 ,勘察手段较多 ,钻探时主要采用了单动双重岩芯管钻具 ,全断面采芯。为突出适用性和经济合理性 ,对场地稳定性、地基基础方案进行了多方面的分析和论证 ,对场地进行了工程抗震评价 ,对深基坑开挖、边坡支护及降水等方面进行了论述 ,满足了超高层建筑岩土工程勘察的要求。

Owing to the importance of this project, many ways of survey are used, drilling tools of single acting double core barrel are mainly adopted while drilling, rock core is taken by full face in order to obtain firsthand drilling record data. The paper analyses and demonstrates site stability and the plan of ground foundation for usability and economic rationalization in different aspects, evaluates site anti?seismic behaviour, discusses in detail digging of a deep pit, supporting of a slope, precipitation and so on. It meets the requirements of rock?soil engineering survey in high?rise buildings.
