钢筋混凝土灌注桩在某工程中的应用

The application of armoured concrete dabbling in a press building

对太原日报社新闻大厦在天然地基承载力不能满足设计要求的情况下 ,对工程地质情况进行了综合分析 ,提出了采用现浇钢筋混凝土灌注桩基的方法 ,根据建筑物上部结构荷载情况 ,对桩基的设计计算与桩的测试数据进行对照 ,证明了桩基设计的正确性 ,又通过对建筑物主体施工过程中和竣工后的沉降观测 ,表明在此项工程中设计人员采用钢筋混凝土灌注桩基的可靠性。

Under the condition that the natural foundation bearing strength of Taiyuan Daily press building can not meet the demand of design, this paper compositively analyzes the geological condition of the construction and proposes the measure of using instant armoured concrete to dablle the stake base. It proves the validity of stake design according to the load on the superstructure of the building, calculation of the stake base design and the comparison of testing data. In addition, the paper testifies the reliability of using armoured concrete dabbling through observation of sedimentation while constructing the main body of the building and after completion.
