本项目研究小湾左岸坝前堆积体在各种工况下的稳定性 ,并研究堆积体所在 2 #山梁下部岩质边坡的可能失稳范围。主要研究内容为 :( 1)堆积体抗剪强度参数三轴试验研究 ;( 2 )堆积体在天然无水、蓄水、无水开挖及地震等工况下的离心模型试验研究 ;( 3 )堆积体边坡在天然无水、滞水、蓄水、无水地震及蓄水地震等工况下的稳定性三维非线性有限元数值分析 ;( 4 )堆积体边坡在天然无水、滞水、无水地震及蓄水地震等工况下的二维、三维极限平衡分析
This project studies the stability of the sediment body in front of the dam on the left bank of Xiaowan under various conditions and studies the possible instability range of the rock slope in the lower part of No.2 # Beam where the sedimentary body is located. The main research contents are as follows: (1) Three-axis experimental study of shear strength parameters of pile body; (2) Centrifuge model test of pile body under natural water, water storage, waterless excavation and earthquake; 3) Three-dimensional non-linear finite element numerical analysis of the stability of the pile slope under the conditions of natural water-free, stagnant water, water storage, anhydrous earthquakes and water-storage earthquakes; (4) , Two-dimensional and three-dimensional limit equilibrium analysis under stagnant water, anaerobic earthquakes and water-storage earthquakes
