单桩水平静载试验主要用于确定桩基的水平承载力,其次用来了解桩基在水平荷载的作用下其内力变化和位移变形。通过实际桩基检测项目采用慢速维持荷载法结合钢筋应力测试技术对单桩水平静载试验所涉及的大部分试验参数进行测试,对桩基水平抗力、拉-压应力、弯矩、挠度及土抗力-位移变化等参数进行计算,详细地分析试验桩基在水平荷载的作用下的变化状态及结果。
The horizontal static load test of single pile is mainly used to determine the horizontal bearing capacity of pile foundation, and secondly to understand the internal force variation and displacement deformation of pile foundation under the horizontal load. Most of the test parameters involved in the horizontal static load test of single pile are tested by using the method of slow maintenance load combined with steel bar stress test through the actual pile foundation test project. The horizontal resistance, tensile-compressive stress, bending moment, deflection and Soil resistance - displacement and other parameters to calculate the detailed analysis of the experimental pile foundation under the action of horizontal load change status and results.
