| 摘 要： | 利用有限元方法,探求长期反复堆卸载过程中桩土相互作用的应力应变情况.研究堆卸载过程中被动桩与土体不同时刻的水平位移、变形、沉降、孔隙水压力变化,以及桩身弯矩等对反复荷载下桩土相互作用的规律,通过改变不同的条件来判断影响桩土相互作用的因素.结果表明:土体在反复堆卸载下不同于静力荷载的应力应变表现,在每个堆卸载过程后,都有...

| Abstract: | The soil-pile interaction behavior subjected to long-term repeated surcharge load is analyzed by the finite element method.The various indexes-time during the load were presented,such as horizontal displacement,deformation,settlement,pore water pressure and pile bending moments.The effect factors under different conditions were studied.It is concluded that the soil behavior of stress and strain performance under repeated surcharge load is different from that under the static load.There is an unrecoverable r... |
