摘要
为研究型钢水泥土复合构件中型钢与水泥土之间的相互作用,进行了型钢水泥土复合构件在型钢受轴向拉力作用下的室内试验,得到了粘结应力沿构件全长的分布规律和构件内某点粘结力的变化规律。证明在试验所用的水泥土强度条件下,型钢与水泥土有效锚固长度为构件全长,且构件破坏时锚固长度内各点均达到极限粘结应力。
In order to study the interaction between profile bars and cement soil in profile bars reinforced cement soil composite components,indoor test is carried out on profile bars reinforced cement soil composite component under axial stress.The distribution rule of bond stress along component length and the changes rule of bond stress of some point are educed.It is proven that under cement soil strength for the test,the effective anchorage length of profile bars and cement soil is the total length of component and each point of component within anchorage length reaches ultimate bond stress in case of failure.
