Analysis on the pre-stress loss of pre-stressed anchors in loess under water action

The author made an uplift model test on anchors in loess,to study the pre-stress loss of pre-stressed anchors in loess under water action.On the basis of data obtained from the test,the author obtains the pre-stress loss of pre-stressed anchors in loess with time and the curve of pre-stressed anchors bolt head displacement with time.With focus on the analysis and discussion,the author draws a conclusion that the pre-stress loss of pre-stressed anchors in loess was caused mainly by creep of soil,...
