Aiming at the problem of failure path analysis of high arch dams, the current numerical simulation methods still do not take into account the tensile and compressive damage characteristics of dam concrete. Therefore, the concrete damaged plasticity (CDP) constitutive model was used to analyze the damage and failure characteristics of the Laxiwa arch dam under the conditions of static overload, sudden temperature drop and maximum credible earthquake. The results show that the dam body mainly suffers from the tensile failure of concrete at the dam heel and bank slope dam foundation under overload conditions, and loses its bearing capacity after the damage penetration zone is formed; Under the condition of sudden temperature drop, the concrete of the dam body may cause tensile damage in the surface hole and the 1/4 arch dam crest, arch end and dam heel area; While under the earthquake condition, the surface hole near the crown beam of the dam crest downstream surface is mainly used for tensile damage. Tensile failure is dominant, and a horizontal band-shaped failure area is gradually formed and the bearing capacity is lost. The research results clarified the possible damage characteristics and failure paths of the Laxiwa arch dam, and provided a reference for determining the key parts of the Laxiwa arch dam structural safety monitoring analysis.

针对高拱坝破坏路径分析的问题,当前数值模拟方法对坝体混凝土的拉压损伤特性仍考虑不足。为此,采用混凝土塑性损伤(CDP)本构模型,模拟分析了拉西瓦拱坝在静力超载、气温骤降及最大可信地震工况下的损伤破坏特性。结果表明,超载工况下坝体主要以坝踵、岸坡坝基处的混凝土拉伸破坏为主,并在形成损伤贯通区后失去承载力;气温骤降工况下坝体混凝土在表孔及1/4拱坝顶、拱端及坝踵区域可能产生拉伸损伤;地震工况下则主要以坝顶下游面表孔拱冠梁附近的拉伸破坏为主,逐渐形成水平带状破坏区域而失去承载力。研究结果明确了拉西瓦拱坝可能出现的损伤特性及破坏路径,为确定拉西瓦拱坝结构安全监测的关键部位提供了参考。

针对高拱坝破坏路径分析的问题,当前数值模拟方法对坝体混凝土的拉压损伤特性仍考虑不足。为此,采用混凝土塑性损伤(CDP)本构模型,模拟分析了拉西瓦拱坝在静力超载、气温骤降及最大可信地震工况下的损伤破坏特性。结果表明,超载工况下坝体主要以坝踵、岸坡坝基处的混凝土拉伸破坏为主,并在形成损伤贯通区后失去承载力;气温骤降工况下坝体混凝土在表孔及1/4拱坝顶、拱端及坝踵区域可能产生拉伸损伤;地震工况下则主要以坝顶下游面表孔拱冠梁附近的拉伸破坏为主,逐渐形成水平带状破坏区域而失去承载力。研究结果明确了拉西瓦拱坝可能出现的损伤特性及破坏路径,为确定拉西瓦拱坝结构安全监测的关键部位提供了参考。

Aiming at the problem of failure path analysis of high arch dams, the current numerical simulation methods still do not take into account the tensile and compressive damage characteristics of dam concrete. Therefore, the concrete damaged plasticity (CDP) constitutive model was used to analyze the damage and failure characteristics of the Laxiwa arch dam under the conditions of static overload, sudden temperature drop and maximum credible earthquake. The results show that the dam body mainly suffers from the tensile failure of concrete at the dam heel and bank slope dam foundation under overload conditions, and loses its bearing capacity after the damage penetration zone is formed; Under the condition of sudden temperature drop, the concrete of the dam body may cause tensile damage in the surface hole and the 1/4 arch dam crest, arch end and dam heel area; While under the earthquake condition, the surface hole near the crown beam of the dam crest downstream surface is mainly used for tensile damage. Tensile failure is dominant, and a horizontal band-shaped failure area is gradually formed and the bearing capacity is lost. The research results clarified the possible damage characteristics and failure paths of the Laxiwa arch dam, and provided a reference for determining the key parts of the Laxiwa arch dam structural safety monitoring analysis.
