| 摘 要： | 由于黄河三角洲特殊的地质地貌及水动力特征，而在本区形成一种工程地交差的软土沉积，总观其自然环境，影响其稳定性的动力因素主要是地震和波浪。根据极限平衡理论，线性波动理论等，计算了地震设计烈度７度和８度地震作用时及５０年一遇的波浪作用时分别在软土土层中不同深度处产生的地震剪应力和波浪剪应力，与其相应软土层的不排水强度相比较可判断，本区软土在５０年一遇波浪和７度、８度地震作用时能滑动破坏。

| Abstract: | Soft soil sediment with poor geotechnical properties was formed in the Huanghe Delta because of the particular geomorphological and hydrodynamic feature Generally observatious of the natural environment show that earthquake and wave are the main dynamic factors to affect the stability of soft soil The earthquake and wave shear stresses at different depth of soft soil caused by earthquake at design intensity 7 and 8 and wave loading apprearing once every fifty years are calculated by using the limit equilibrium and linear wave theory Comparing the shear stress with undrain strength of soif soil layer, possibility of shearing failure could be evaluated |

| Keywords: | Huanghe subaqueous delta soft soil shear stress undrain strength |
