浅基础在湖南邵阳某高层建筑中的应用
摘要:强调了对覆盖层进行精心勘察在高层建筑中的重要性,指出特定地质条件下浅基础在某些高层建筑中的可行性。从土工试验、原位测试入手,对地基土体承载力及其变形进行分析,同时查明了场地的水文地质条件,在此基础上结合拟建工程特征提出了两种基础方案。然后从施工、经济、安全、环境各方面进行对比论证,最终确定采用浅基础方案。方案实施后,建筑物沉降观测最大沉降量仅5.0mm,平均沉降量3.4mm,远小于国家规范的限值;另外,相对传统嵌岩桩基础,该方案节省成本约80万元,缩短工期约2个月。因此,一定地质条件下,在某些高层建筑中采用浅基础是可行的,而且能节约成本、缩短工期。
Abstract:The authors mainly introduce the application of shallow foundation in Shaoyang of a high-rise building in this paper, and emphasize the importance of elaborately investigate in overburden when in high-rise buildings, and also point out the feasibility of shallow foundation in some high-rise buildings at certain geological conditions. According to the results of soil test and in-situ test, the bearing capacity and deformation of the soil have been analyzed. At the same time, the authors reveal the hydrogeology conditions, and put forward two foundation projects. At last, the shallow foundation has been adopted basing on factors of construction, economy, safety and environment. The largest settlement is only 5.0mm and the average value is 3.4mm, which is far less than the national standard limits, after the project having been completed. In addition, this scheme save cost about 800 thousand yuan and shorten the construction period about 2 months comparing with the traditional rock-socketed pile foundation. So, the shallow foundation can be adopted in high-rise buildings at certain geological conditions, it can save cost and shorten the construction period.
