桩端岩基承载力特征值的确定

Determination of Characteristic Value of Bearing Capacity of Rock Base at Pile End

该文以岳阳市某商业广场工程为例 ,通过数理统计方法对室内岩石单轴抗压强度试验和室外岩基载荷试验原始数据进行处理 ,得出安全合适的岩基承载力特征值和经济合理的桩长 ,最后对整个场地作出综合评价。

As an example of Yueyang City commercial square project,the paper uses mathematical statistics methods to process original data of the laboratory rock uniaxis compressive strength test and in-situ rock base loading test,and obtains safety and suitable characteristic value of bearing capacity of rock base and reasonable economic pile length,then makes integrated evaluation for the whole site.
