ANALYSIS ON HARMFULNESS OF EMBEDDED CRACK IN SPILLWAY PIER AND ITS TREATMENTS
溢洪道闸墩裂缝危害性及处理措施分析

A numerical analysis of cracks in the pier of spillway in a water conservancy work is carried out with the unique crack elements to simulate the cracks and the special bolts crossing crack element. The results of the numerical analysis show that the deformation of the cracks under the external loads may be unstable if the cracks are not treated. The treatment parameters of chemical grouting are also given by the simulation analysis.
