Foundation pile static load testing method based on flat plate load tester
The invention discloses a foundation pile static load testing method based on a flat plate load tester, and belongs to the field of geotechnical investigation. The foundation pile static load testingmethod comprises the following steps that firstly, a hydraulic cylinder is installed, a pile head is placed on a foundation pile, and the hydraulic cylinder is placed on the pile head; secondly, a supporting frame is erected, the supporting frame comprises pier bases and first supporting beams, the pier bases are placed on the ground on the two sides of the pile head, the first supporting beams are erected on the pier bases, and a plurality of balancing weights are arranged above the first supporting beams; thirdly, a reference beam is erected, namely, a horizontal reference beam is erected, and the two sides of the reference beam are fixedly connected to the pier bases; fourthly, a dial indicator is installed, a base of the dial indicator is installed on the pile head, and the detection end of a head of the dial indicator is abutted against the reference beam; and fifthly, detection is conducted, the hydraulic cylinder is started, the upper end of the hydraulic cylinder is abutted against the lower ends of the first supporting beams, and the reading of the dial indicator under different pressures of the hydraulic cylinder is recorded. The foundation pile static load testing methodhas the effect that the accuracy of settlement testing data of the foundation pile under different pressures is improved.
本发明公开了一种基于平板载荷测定仪的基桩静载荷测试方法，属于岩土勘察领域，其包括以下步骤：步骤一：安装液压缸，将桩头放置于基桩上，将液压缸放置于桩头上；步骤二：架设支撑架，支撑架包括墩座和第一支撑梁，墩座放置于桩头两侧的地面，第一支撑梁架设在墩座上，在第一支撑梁上方设置多个配重块；步骤三：架设基准梁，架设水平的基准梁，基准梁两侧固定连接于墩座；步骤四：安装千分表，将千分表的底座安装于桩头，所述千分表表头的检测端抵触基准梁；步骤五：检测，启动液压缸，使液压缸的上端抵触于第一支撑梁下端，记录液压缸不同压力下千分表的读数。本发明具有提高了基桩在不同压力下沉降量测试数据准确性的效果。
