近年来专家们越来越重视土工建筑物和地基稳定性的三维计算问题,并已提出一系列方法以图在设计方案内算出具有宽度不大的三维塌滑体[参考文献1—6]。在外形复杂的深谷中,设计和建筑高坝(例如:努列克坝和罗贡坝等)时,这种计算方法的现实意义正在逐渐增长。本文所提的研究方法以下列假定为基础。 In recent years, experts have paid more and more attention to the three-dimensional computational problems of the stability of geotechnical buildings and foundations. A series of methods have been proposed to calculate three-dimensional slump with little width in the design scheme [References 1-6]. In the complex deep valleys, the practical significance of this method of calculation is gradually increasing when designing and constructing high dams (eg, Nureck and Rogon). The research method presented in this paper is based on the following assumptions.
