摘要
采用三维有限元方法对底孔闸墩裂缝成因进行了分析研究,考虑了各种可能产生裂缝的影响因素,并对温降进行了敏感性分析。研究结果表明:闸墩在正常的结构荷载作用下不会产生裂缝,温度骤降是产生裂缝的根本原因。
The reasons for the cracks at the bottom orifice pier are analyzed by three-dimensional finite element method. The influencing factors for the cracks formation are taken into account, and the sensitivity analysis is conducted for the temperature drop. The results of the study show that cracks are not formed in the normal structure load, but abrupt temperature drop is the main reason for cracks formation.
