兰州地区第三系风化砂岩超高层建筑地基基础方案比选

Comparison and selection of foundation schemes in tertiary weathered sandstone of a super high-rise building in Lanzhou

通过具体实例工程的岩土工程勘察,采用多种手段现场勘探测试工作和岩石力学试验,提供了第三系风化砂岩的物理力学指标,对地基基础方案进行了比选和建议,为兰州地区同类工程的勘察和地基探索提出了有针对性的评价方法,积累了宝贵的经验。

In this paper,the physical and mechanical indexes of the tertiary weathered sandstone are provided through the geotechnical engineering investigation of a specific project,the field exploration and testing work and the rock mechanics test by various means.The comparison and selection of the foundation scheme are carried out,and valuable experience is accumulated for the exploration of similar projects and the foundation in Lanzhou.
