【摘要】 以粘土横向静载桩P-Y曲线统一法为基础,借助于现场试桩试验及Matlock、Reese等试桩资料,研究了周期性荷载作用下极限土抗力退化和土应变软化等桩土相互作用特点,提出了适用于各种粘土的横向周期性荷载桩的P-Y曲线统一法.该方法经国内外若干地区现场试桩结果检验,计算值与实测值符合良好.更多还原

【Abstract】 On the basis of the unified method of P-Y curves of laterally and statically loaded piles in clay, the field tests and the pile testing results of Reese and Matlock, the authors have studied the reduction of limit soil resistance and the softening of soil strain under the action of lateral and perioadical load, and proposed a unified method of P-Y curves for laterally and periodically loaded piles in various kinds of clay. Field tests at home and abroad show that the calculated value is in good agreement with the measured data.更多还原
