| 摘 要： | 结合亭子口水利枢纽升船机上闸首坝基深层抗滑稳定研究,采用非线性有限元法对坝基软弱夹层及抗滑齿槽受荷破坏过程进行了计算分析。为考证齿槽周边坝体混凝土是否会先于软弱夹层屈服,考虑坝体材料为非线性本构关系,并将计算成果与坝体材料为线性本构关系的结果进行比较,分析认为坝体为非线性材料时计算出来的安全系数较小。计算表明,升船机上闸首在设置抗滑齿槽后,整个坝基系统的安全系数较高,坝基深层抗滑稳定是安全的。

| Abstract: | Based on deep anti-sliding stability analysis for upper lock head of Tingzikou Hydro-junction ship lift,the failure process of soft intercalation and anti-sliding cogging of the dam foundation is calculated by nonlinear FEM method.To investigate whether the cogging concrete yield before the soft intercalations or not,the dam material is considered as nonlinear constitutive relation,and the calculation results are compared with linear constitutive relation materials.It is shown that the safety factor calcula... |
