PHC tubular pile horizontal bearing capacity testing method
The invention provides a PHC tubular pile horizontal bearing capacity testing method. The PHC tubular pile horizontal bearing capacity testing method comprises the steps that 1, a test pile serves asthe center, and a frame perpendicular to the test pile is installed on the periphery of the test pile; 2, a counter-force device is loaded between the frame and the test pile; 3, a jack is placed between the top of the test pile and the counter-force device, the load capacity is tested through the jack, one mold is that the load capacity is directly measured through a load sensor arranged on the jack, the other mode is that the jack oil pressure is measured through a pressure gauge or a pressure sensor, and the load is converted according to a jack calibration curve; 4, a displacement sensor is installed between the frame and the test pile, and the displacement sensor or a wide-range dial indicator is adopted; and 5, other test piles are further tested, wherein the number of the test pilesis at least three and not less than 1% of the total number of the test piles. According to PHC tubular pile horizontal bearing capacity testing method, the counter-force device is formed to test theload capacity of a PHC tubular pile, the test pile settlement is tested through the displacement sensor, and the numerical value is directly read through the sensor, so that the operation is convenient.
本发明所提供的PHC管桩水平承载力测试方法，步骤一、以试桩为中心，在试桩周围安装于试桩垂直的边框；步骤二、边框和试桩之间加载反力装置；步骤三、在试桩顶部与反力装置之间放置千斤顶，通过千斤顶测试载荷量，一种是由安置在千斤顶上的荷重传感器直接测定；另一种是通过压力表或压力传感器测定千斤顶油压，根据千斤顶率定曲线换算荷载；步骤四、边框和试桩之间安装位移传感器，采用位移传感器或大量程百分表；步骤五、进一步地测试其他试桩，试桩数量至少为三根且不少于总桩数的1％。本发明通过形成反力装置测试PHC管桩载荷量，并通过位移传感器测试试桩沉降，通过传感器直接读取数值操作便利。
