柬埔寨甘再重力坝深层抗滑稳定分析

Analysis on deep anti-sliding stability for construction of Kamchay Gravity Dam in Cambodia

结合柬埔寨甘再重力坝工程,采用弹塑性有限元强度折减法,根据特征点位移突变及坝基整体塑性区贯通情况,得到正常蓄水位下的该坝坝基深层抗滑稳定安全系数。计算结果表明,甘再重力坝深层抗滑稳定安全度较高,满足规范要求。

Combined with the actual construction of Kamchay Gravity Dam in Cambodia,the deep anti-sliding safety coefficients of the dam foundation under the normal storage level of the reservoir are obtained with the elastoplastic strength-reduction finite element method in accordance with the case that if a sudden change of the characteristic point shift occurs and the plastic zones under the whole dam foundation are connected throughout. The calculation result shows that Kamchay Gravity Dam has a higher safety degree of stability against deep slide therein,and then can meet the requirement of the specification concerned.
