发布时间:2019-05-27 22:06
【摘要】:通过数值模拟,对比基桩试验结果和模拟结果,验证计算模型的适用性。计算不同荷载等级下桩身的内力分布情况和位移变化,分析桩身稳定性;对桩周土体的受力状态进行分析,研究水平荷载对桩周土体的扰动情况。研究结果表明:在受到长期性的横向荷载作用时,桩身会受到持续的剪切作用,应定期进行桩身完整性检测;在水平荷载的作用下,基桩周围的土体会受到剪切和张拉作用。
[Abstract]:Through numerical simulation, the applicability of the calculation model is verified by comparing the test results and simulation results of foundation pile. The internal force distribution and displacement change of pile body under different load grades are calculated, the stability of pile body is analyzed, the stress state of soil around pile is analyzed, and the disturbance of horizontal load to soil around pile is studied. The results show that the pile body will be subjected to continuous shear action when subjected to long-term transverse load, and the pile integrity should be tested regularly, and the soil around the foundation pile will be subjected to shear and tension under the action of horizontal load.
