高层建筑物地基工程勘察实例分析

Analysis on Geotechnical Engineering Survey for Foundation of Highrise Buildings

本文以徐州市华电大厦地基的岩土工程勘察为研究实例 ,论述了高层建筑地基岩土工程勘察所需进行的技术工作方法 ,通过对该建筑物地基土各土层的物理力学性质的现场原位测试和室内土工试验结果的分析 ,根据规范计算法和应用静力触探资料法 ,探讨了本工程实例正确选择桩尖持力层及桩型的问题。本工程实例的研究与分析 。

Taking the geotechnical engineering survey for the foundation of Huadian Building in Xuzhou City as an example,the technical methods applied for geotechnical engineering survey of foundation of highrise buildings were discussed.Based on in_situ test of physico_mechanical properties of ground layers from the foundation of the building, analysis of laboratory geological test results with caluclation according to regulations and data from static probing, the problems for selection of bearing layer for pile tip and types of piles were investigated.This work can serve as reference for similar engineering works.
