中文摘要:
      坝基深层滑动面的产状及组合一般可分为单斜面滑动、双斜面滑动和多斜面滑动,其中双斜面滑动 最为常见。本文在阐述坝基的单滑面和双滑面两种滑移模式的计算原理、安全判据等的基础上,用等安全系 数法计算向家坝水电站泄12 坝段的安全系数,分析了抗力角φ 的变化对安全系数的影响及第二滑裂面最不利 的位置及其对安全系数的影响。计算结果表明,随着φ 角的增大,安全系数逐渐增大,从安全角度出发,工 程上一般取φ=0。
英文摘要:
      The occurrence and combination of deep sliding surface of dam foundation can generally be divided into single- slope sliding,double-slope sliding and multi-slope sliding,of which double-slope sliding is the most common. On the basis of explaining the calculation principle and safety criterion of the two slip modes of single slip surface and double slip surface of dam foundation,this paper calculates the safety factor of Xiangjiaba Hydropower Station Section 12 by using the method of equal safety factor,analyses the influence of the change of resistance angle on the safety factor, and studies the most disadvantageous position of the second slip surface and its influence on safety factor.The calculation results show that with the increase of the resistance angle,the safety factor increases gradually. From the point of safety,the resistance angler is generally equal to zero in engineering.
