摘要
为研究微型抗滑桩加固边坡的力学机理,对微型抗滑桩应变与埋深的关系进行了一系列室内模型试验研究。试验结果表明:在坡顶荷载作用下,同一埋深时位于坡顶抗滑桩所受应变小于位于坡中部抗滑桩,而同一排抗滑桩所受应变基本相等;不同埋深对基桩应变影响规律基本一致,即应变在桩顶以下小范围达到最大值,之后随着埋深增加而减小,在到达0后出现反向应变,反向应变达到最高值后衰减到0。
In order to study the mechanical mechanism of micro-piles reinforced slope,a series of laboratorial model tests are carried out to investigate the relationship between the strain and the embedded depth of the micro-piles.The results show that the strain of the micro-piles on the top of slope is less than the middle slope at the same embedded depth and the strains of the same row micro-piles are basically equal under load on slope top.The rule of influence of the strain at different embedded depth is basically consistent,which means the strain of the micro-pile reaches the largest value in a small range below the top of the micro-pile and decreases with the embedded depth.The reverse strain appears after the value reaches zero,the reverse strain reaches the peak value and then decays to zero.
