针对水下边坡稳定尚无成熟的计算方法 ,采用搜索法对水下粉砂质边坡和水下细砂质边坡的极限坡率进行离心模型试验。通过 13组模拟试验结果表明 ,水下粉砂质边坡的极限坡率陡于水下细砂质边坡的极限坡率 ,而后者接近于细砂的抽板法水下天然休止角
Aiming at the unskilled calculation method of underwater slope stability, the centrifugal model test of the ultimate slope of submarine silty slope and underwater sub-sandy slope is carried out by using search method. The results of 13 groups of simulations show that the ultimate slope of submarine silty slope is steeper than the limit of submarine sandy slope, while the latter is close to the natural angle of repose
