摘　　要：工程地质调查发现苏州渔阳山边坡稳定性受软弱夹层控制,通过现场制样对软弱夹层进行原位大型剪切试验得到软弱夹层的强度参数为c=71.86 kPa,φ=22.1°,根据试验结果计算得不同工况下边坡稳定性系数与边坡实际稳定性情况一致,表明该试验方法和试验结果可靠,可作为边坡稳定性评价和加固设计的依据。By engineering geology investigation,it is found that the stability of the Yuyangshan slope is controlled by the weak interbedded layer.The strength parameters of the weak layer is c=71.86kPa,φ=22.1° which were tested by the large-scale shear test in situ.The stability factor the slope can be calculated under different work condition,the calculation results are consistent with the actual situation,which indicate that the test method is reliable,and the results could be used as the basis of the stability evaluation and reinforcement design for the slope.
