Besides, thevarious stress distribution of the soil mass around the anchorage end iscompared with regard to different grid density by densifying the soil element. 对预应力锚筋锚头周围的土体单元进行加密,比较了不同网格密度情况下锚头附近土体的应力分布情况。
When the initial prestressing value varies, the relations between structural bearing capacity and member initial curvature are similar and nearly linear. 在不同初始预应力取值下,极限荷载随杆件初始弯曲变化的规律相似,并且都接近于线性。
An approach is also deduced to predict the residual stress under conditions of reloading. 该表达式可用于拟合松弛试验结果,并根据试验结果预测不同初应力时的应力松弛行为。
