摘要
采用二维有限差分程序对龙口水利枢纽混凝土重力坝厂房坝段进行深层抗滑稳定分析,采用强度折减方法,根据特征点位移突变临界破坏判据和止水帷幕部位夹层错动量达到1mm临界破坏判据分别得出了厂房坝段的两个深层抗滑稳定安全系数。分析结果认为采用夹层错动量达到1mm作为强度折减法临界破坏判据更适合该工程。厂房坝段基本组合深层抗滑稳定安全系数偏小,应采取一些加固措施。
The 2D Elastoplastic Finite Difference Method is adopted to analyze the deep anti-sliding stability for the dam foundation of Longkou hydropower station factory dam. This paper, based on the anti-shear parameters reduction with specific point displacement, calculates two safety factors, with the results showing that the discontinuity in the water-resisting curtain sliding distance 1 mm fits to Longkou project. The calculation demonstrates that the deep antisliding stability can not be guaranteed unless some reinforcement is applied.
