Besides, thevarious stress distribution of the soil mass around the anchorage end iscompared with regard to different grid density by densifying the soil element. 對預應力錨筋錨頭周?chē)耐馏w單元進(jìn)行加密，比較了不同網(wǎng)格密度情況下錨頭附近土體的應力分布情況。
When the initial prestressing value varies, the relations between structural bearing capacity and member initial curvature are similar and nearly linear. 在不同初始預應力取值下，極限荷載隨桿件初始彎曲變化的規律相似，并且都接近于線(xiàn)性。
An approach is also deduced to predict the residual stress under conditions of reloading. 該表達式可用于擬合松弛試驗結果，并根據試驗結果預測不同初應力時(shí)的應力松弛行為。
