| 摘 要： | 本文针对前人推导的水平荷载桩地基土极限水平反力Pu的基本假设不尽合理和所得Pu过大、偏于不安全这一现象,对水平荷载桩地基土极限水平反力的形成特征和桩周土的应力状态进行了分析研究.并在此基础上按塑性理论推导获得了无粘性土中圆形截面水平荷载桩地基土极限水平反力Pu的滑移线理论解,其Pu值约为Broms建议值的一半或更小.经与试桩资料对比,本文解答求得的单桩极限水平承载力与实测值非常吻合.

| Abstract: | According to the study on characteristics of the ultimate lateral resistance of laterally loaded pile in cohesionless soil and the behavior of stress in soil around pile, a solution of theultimate lateral resistance Pu of circular piles by sliding line theory has been derived, and it is found that the values of Pu are about half of those suggestd by Broms. The ultimate lateral bearing capacity at the top of the pile obtained by the solution is in good agreement with the measured one. |
