摘要

拱坝坝肩高边坡的稳定性问题是当前工程研究的热点问题之一。当前

坝肩边坡作为从属工程

其稳定性的分析主要是针对边坡本身的稳定性进行的。分析中采用的判定从属边坡稳定性的评价标准并不能保证主要坝体的安全性。为了使边坡的抗滑安全性计算中能考虑坝体的影响

作者提出了“从属安全度”概念

并基于应力控制标准给出了从属安全度的计算公式。以某高拱坝为例进行了坝肩边坡的从属稳定性数值试验研究

研究结果表明:考虑边坡动力反应过程中坝体稳定性

坝肩边坡的从属稳定性系数将降低20%。

Abstract

The "hypotaxis stability" concept and the dynamic stress hypotaxis safety ratio method were presented in order to take the safety of arch dam into consideration because the safety coefficient does not assure the safety of dam.A three dimension dynamical contact unit model was developed to illustrate fractured rock mass of the dam abutment slope.Using the 3D-dynamical constraint joint element

certain dam abutment slope system was analyzed.Numerical analyses show that: with dynamic stress hypotaxis safety ratio method and the three dimension dynamical contact unit model

the "hypotaxis safety ratio" of abutment slope can be decreased by 20%.
