在具有软弱夹层岩基上设计重力坝时必须考虑深层滑动稳定问题.本文将此稳定条件引入混凝土重力坝的断面优化设计,建立了适合于序列二次规划法计算的优化数学模型.根据大量优化计算结果,从断面优化的角度,较详细地分析了岩基中软弱夹层的性状(诸如摩擦系数、倾角和埋藏深度等)对这类大坝设计的影响规律,提供了一些对大坝设计有参考价值的信息.
In the design of gravity dam with weak intercalated rock foundation, the deep sliding stability problem must be considered.In this paper, the stability condition is introduced into the cross-section optimization design of concrete gravity dam, and the optimal mathematical model suitable for the calculation of sequence quadratic programming method is established.According to a large number of optimization From the point of view of section optimization, the influence of the characteristics of soft interlayer in the rock foundation (such as friction coefficient, dip angle and burial depth) on the design of such dams is analyzed in detail.
