基于综合勘察方法评价兰州某超高层建筑软岩地基承载力

Evaluation of Bearing Capacity of Soft Rock Foundation of a Super High-rise Building in Lanzhou based on Comprehensive Investigation Method

该文以兰州某超高层建筑为例,通过采用现场钻探、旁压试验、室内岩石试验等综合勘察方法,对场地新近系软岩地基承载力进行了分析评价,提出了可靠的地基承载力参数,并通过载荷试验予以验证,为兰州城区超高层建筑工程地质评价提供了有力的依据,可供相关技术人员参考。

Taking a super high-rise building in Lanzhou as an example,the comprehensive exploration methods such as on-site drilling,lateral pressure testing and indoor rock testing are used to analyze and evaluate the bearing capacity of the neogene soft rock foundation on the site.The reliable parameters for the bearing capacity of the foundation are proposed,and later verified through load tests,which provides a strong basis for the geological evaluation of super high-rise buildings in Lanzhou urban area and reference for relevant technical personnel.
